How to connect the antenna cable correctly. How to connect the antenna cable to each other

In the heyday of satellite and cable television, especially for city dwellers living in apartment buildings, the question of installing a television antenna on the roof almost never arises. This problem is still relevant for arranging television broadcasting in a country house or in a private house outside the city. Satellite TV is an expensive thing, not every person will allow himself to spend solid money on buying a satellite TV receiver as a country option, so the rational way out is to purchase an analog receiver and fix it yourself. In this article, we will tell readers how to install an antenna on the roof of a private house.

Antenna mounting options

After the antenna is purchased, before installation, you need to make sure that the accessory fasteners are available and pre-treat its threaded part with lithol or machine oil, in extreme cases, with silicone grease or WD-40. If you decide to install an active antenna, in order to prevent oxidation of the contact points, it is recommended that after completing the connection of the cable to electronic board seal it with waterproof silicone.

Depending on the power and direction of the television signal, a decision is made on the location and height of the antenna installation. In practice, two options are most popular: on the facade of the house and on the roof. Consider both mounting technologies.

On the front of the house

The easiest and least time consuming option. You can install a television antenna on the facade yourself without anyone's help, but this method has a significant drawback. To ensure reliable reception, the signal of the nearest repeater must be of such power that the receiving device does not need to be raised high. The choice of this installation option limits the material and decoration of the walls of the house. It is impossible to install on siding and it is very problematic on aerated concrete masonry. The ideal option for installing the antenna on the facade wall is when it is made of brick or wood. When performing installation, it is necessary to maintain a distance between the fasteners at a distance of no more than 1.5 meters. It is recommended to use anchor bolts or self-tapping screws as fastening material.

1. Receiving antenna device.
2. Metal pipe or wooden beam.
3. Bracket.
4. Anchor bolt (self-tapping screw).

The video below clearly demonstrates how to install a receiving antenna device on the facade of a house:

Even in the age of digital technology and the total penetration of the Internet into all spheres of life, many apartments receive a television signal via cable. The wrong attitude to its installation can negatively affect the quality of the received signal, even in the case of choosing the most modern and expensive material. In the article we will tell you how to connect a TV cable different ways, we will give recommendations to beginners.

Features of the cable

The television cable “comes” into the apartment from the floor board and is routed through the television receivers available in the house. In order to properly wire the TV cable around the apartment, you should follow some recommendations.

To avoid interference with the signal, it is recommended to place the cable away from the electrical wiring. A telephone wire or cable for the Internet does not interfere with the normal passage of a TV signal, and therefore the general laying of these communications in one cable channel is allowed. If it is impossible to avoid the joint placement of the electrical cable with the television, then you should purchase a TV cable with a core diameter of more than 1 mm with a double protective screen.

Throughout the apartment, the cable should be pulled in one piece, avoiding any connections and twists that affect the quality of the picture. Crossing the cable with electrical networks is not recommended, but if this cannot be avoided, then the intersection should be arranged strictly at an angle of 90 °. Read also the article: → "".

Cable distribution by rooms to ensure shielding and high quality contacts and is carried out using factory-made splitters. Do-it-yourself devices are unlikely to be able to give an acceptable signal quality. You should also avoid connecting television cable with sharp bends or in a bay - the quality of the picture on the screen can suffer greatly from this.

It is better to lay the section of the line going from the floor box to the apartment in an expanded cable channel, taking into account the possible activation of an alarm or additional telephone line. To facilitate maintenance, splitters should be placed in places with free access.

How to choose the right cable

Even the most modern TV receiver and cable plugs cannot produce an acceptable image with an insufficiently high-quality cable. High-frequency TV signal currents flow a little differently than home electrical currents. The higher the frequency of the current, the closer to the edges of the main wire it flows, therefore, in the cables used in the military or space industry, in order to avoid a critical decrease in the quality of the television signal, they are treated with a silver or gold composition.

Choosing a cable to connect

When choosing a material, you must adhere to the following recommendations:

• all designations must be present on the outer shell;
• the resistance value of the product should be 75 ohms, because all television receivers are designed for this value;
• the outer diameter must be more than less than 6 mm;
• the main core and the shielding braid must be made of copper.

In the latter case, manufacturers often sin by striving to reduce the cost of products as much as possible by making the central core of steel and simply coating it with copper sputtering, braiding from copper alloys, and shielding from foil. Read also the article: → "".

TV cable marking

Consider the marking on the example of the Chinese television cable RG 6U, the most common in our country.

An example of marking a Russian-made cable with an indication of the main characteristics and specifications

How to connect the cable to the plug

You can connect the plug to the cable on your own, especially since the TV signal voltage is too low to cause any harm to health. Even an unplugged cable is cut without fear of electric shock. There is no harm in shorting between the braid and the main core either. For different sizes of cables, different plugs are produced, therefore, when choosing a cable, you need to pay attention to its diameter. F-plugs are the most commonly used.

First you need to cut the cable, which can be done in two ways:

• with braid bend;
• without twist.

The most reliable method is considered to be cutting with a twist, but if it is not possible to install the plug, then the second method is used. The cable is cut with a scalpel or a sharp knife: the outer sheath is carefully cut along the length without damaging the screen. When the cut is completed, the insulation is folded back and removed.

The copper braid and shielding foil are wrapped. In general, three types of shielding can be applied in TV cables:

• aluminium foil;
• copper braid;
• aluminum foil with copper braid.

Aluminum foil is often coated on the inside with polyethylene for reinforcement purposes. It is unlikely that it will be possible to strip the film without damaging the foil, therefore, to improve the contact of the screw-on plug with the foil, its bent part is slightly wrapped back so that the uninsulated piece of foil faces outward. If the cable diameter is too small, the end entering the plug is wrapped with electrical tape.

The insulation from the main core is removed in the usual way for many, similar to the removal of insulation from electrical wires without damaging the core itself. Then the plug is wound onto the foil, and the excess of the main core is bitten off with wire cutters or cut off with a knife, leaving a length of about 3 mm outside.

Connecting the cable to the antenna

Connecting the TV cable to the antenna should be carried out with the obligatory observance of the rules for switching electrical appliances, guided by the diagrams available in the technical data sheet of the TV. To complete the work you will need:

• splitter;
• antenna cable;
• antenna amplifier;
• wire cutters;
• a sharp knife or scalpel;
• soldering iron.

The antenna amplifier is used when the signal is not strong enough or too weak. A splitter is useful for connecting several TVs to one antenna at once. Read also the article: → "".

The cable is connected directly to the TV antenna using screw clamps.

The cable, splitter and amplifier must be installed next to the routed cable. In an individual house, the best place to place all appliances is the attic. The end of the cable coming out of the antenna is connected to the amplifier through a special terminal. From the amplifier, the signal comes to the splitter, to which the television receivers in the house are connected. When connecting to a satellite dish, you will need to use a receiver to which a cable is connected via the antenna connector. The preparation of the cable is carried out in the same way as cutting it before connecting it to the plug.

Council number 1. Before connecting the TV, you must carefully check all the connections of the switching devices and the reliability of the installation of the plugs in the appropriate sockets. If the image is noisy or the signal is too weak, adjust the antenna amplifier settings.

Connecting to a splitter (splitter)

Nowadays, no one can be surprised by the presence of a TV in every room. A small problem is to feed the TV signal to all receivers, since in most cases the signal source is the same. The solution to this problem is to use an antenna splitter. The quality of the picture when connecting TV receivers through a splitter may deteriorate somewhat, but the connection process itself is not difficult and takes just a few minutes.

The step-by-step connection scheme can be represented as follows:

• choosing the location of the splitter and fixing it in it;
• removing plugs from used connectors;
• cutting and connecting TV cable.

Connecting the cable in the shield

When laying or connecting the cable, it is not allowed to twist it into knots and bays, kinks or sharp bends that sharply degrade the quality of the received TV signal.

Tip number 2: The cable section that goes first from the shield to the apartment should be placed in a wide cable channel.

In the case when the cable connection in the ladder box must be carried out by soldering, the length of unshielded sections should be minimized, since their presence and length directly affects the quality of the signal and image. At the end of soldering, it is recommended to cover each contact under a layer of varnish - it is able to prevent the occurrence of foci of corrosion damage and the ingress of dust particles between the contacts. Dust adhering between the contacts causes the signal to deteriorate with increasing humidity: the image reproduced by an analog TV will snow heavily, and when a digital signal is transmitted, the image will simply disintegrate into pixels with an unpleasant squeak.

Frequently asked Questions

Question number 1. Is the F-plug for digital for digital TV signal transmission, or only for analog?

Despite the fact that this type of plug has been used for a long time, both its connector and characteristics allow you to fully enjoy not only analog (by the way, in the near future, permanently stopping broadcasting) television, but also digital and satellite TV signal.

Question number 2. What to do and what to do if the cable diameter turned out to be slightly smaller than the diameter of the internal thread of the plug? Indeed, in this case, reliable compression will not work.

Question number 3. If you install the plug in the appropriate socket, the TV cannot be placed close to the wall. What is the way out of this situation?

In this case, you should use an angled plug, which can be bought at almost any store selling electrical household appliances.

Question number 4. In old Soviet-made TVs, the cable was connected to the plug by soldering. How to connect to it modern type cable?

If the signal quality deteriorates or the cable needs to be replaced due to poor contact, the plug and cable can be connected as before by soldering.

Question number 5. How can I connect several TVs to an antenna or cable TV network at once?

To connect several television receivers, you can use a special device - a splitter, also called a "divider" or "splitter".

Typical connection errors

• Not everyone knows that the foil in the cable is covered by some manufacturers from the inside with polyethylene, which cannot be cleaned even with a scalpel. Plastic, even with the highest quality cable stripping, will prevent the creation of high-quality contact with the plug. To avoid signal distortion, it is recommended to wrap part of the folded foil in the opposite direction so that the conductive side is outside.
• A typical mistake is getting the thinnest wires of the braid onto the main core of the cable when it is being compressed. Doing so may result in poor quality or intermittent signal dropouts. A common mistake when installing and laying a cable is placing it in the same plinth with electrical wiring. You can't do that, otherwise the generated interference can significantly spoil the mood when watching TV.

Considering the connection of an antenna of any version and design, we can conclude that it happens in almost the same way. An exception, perhaps, will be wireless connections, where is absent by definition. The TV antenna jack is difficult to confuse with the rest of the connectors, but it is important to determine the type of plug that suits your TV.

The most popular TV plug for the F connector is that it copes better than others with the transmission of both digital and digital signals. For use F type connector without TV plug.

How to connect an antenna to a TV

Many still have old versions of TVs, on the back of which you can not find the connector for the F-connector. If you have a suitable plug - great, below we will tell you how to install it on the cable in order to properly connect the TV.

To the public antenna

In apartment buildings, it is often necessary to connect to a common house antenna or to a collective antenna in the entrance. What does it mean? A group of antennas is installed on the building. Most often, this is a “dish” and one or two terrestrial antennas, depending on how many channels are broadcast in the region and from which directions.

Each apartment has a TV outlet. The antennas are connected to a junction box, from which cables diverge to outlets in the apartments. The TV or decoder is connected to the socket in the apartment, not to the antenna on the roof.

TV signal from a professional, well designed installation antenna equipment strong and stable, and interference may be negligible.

Individual passive antenna

Connecting a passive television antenna can be entrusted even to a child (it's safe). All you need to do is plug the cable into the TV or digital tuner jack. Another thing, if the signal is to be divided, then first connect.

Individual active antenna

In active antennas, current is supplied to the amplifier through the same cable through which the TV signal comes from the antenna. Often they use almost identical power supplies. Their design includes a separator - a special television plug in which the TV signal is separated from the supply voltage for the amplifier. Therefore, connecting an active antenna comes down to bringing the coaxial inside the separator and fixing it with an SWA-type clamp, and connecting the separator connector to the antenna input on the TV.

How to install the antenna plug on the cable

They are presented on the market in different standards with different diameters. The girth of the plug must be chosen according to the diameter of the cable. This will ensure uninterrupted and reliable operation of the installation.

Basic tools needed:

• scissors;
• knife (not too sharp);
• pliers (optional).

Installation under F plug

To screw such a popular F-connector onto the cable means to do a set of standard actions:

• cut the wire at a right angle to the desired length;
• cut off the cable sheath with a knife 12-15 mm long (minimum);
• bend the shielding conductors to the outer side of the insulation;
• cut off the inner insulation of the core with a knife, leaving it about 4 - 5 mm;
• Before screwing on the connector, check if the shield is in any way touching the core. Screw the cable termination until it stops by turning it clockwise, pressing it against the cable. If necessary, you can hold the connector with pliers.
• Adjust the length of the central core so that the protrusion of the cable core is up to 1 - 2 mm.

Installing the screw plug

Before the invention of F-type cable terminations, connectors of a slightly different, but in their own way advanced design were used, which also did not need to be soldered, but were put on the cable according to a different algorithm.

Installing the TV plug under the screw

Many still have them on the farm, so let's find out how to use it when connecting to an antenna.

So, the body of this connector consists of plastic and metal parts. The plastic part is removable. It must be unscrewed from the metal part and a cable threaded into it (so you won’t forget about it and won’t lose it).

Next - prepare the edge of the cable where the plug will be mounted. Remove a centimeter-long cylindrical section of the outer sheath of the wire with a sharp knife. The braided screen layer that has been opened must be shortened by 5 mm from the edge of the cable. Together with it, cut off the core insulation. Thus, you will get a processed end of the cable with successively offset layers, where the central core protrudes forward.

Thread the coax into the plug as follows: place the clamp for contact with the screen over the braid (it must be crimped around the cable), and pass the main core into the screw fastener and tighten it until it stops. Now you need to restore the integrity of the plug by winding its polymer part onto the metal.

Installing the solder plug

Although the soldered plug can be safely attributed to relics, it must be admitted that it provided excellent contact and is still relevant in combination with multi-wire flexible RF cables such as RK-75-4-12 and similar in structure.

In addition to the plug and cable, you will need:

• soldering iron, tin or rosin;
• cable stripping knife;
• a small metal file or needle file that will be used to clean the soldering field;
• multimeter, ohmmeter or light bulb to check the contact of the plug.

Now to business. We remove the outer (black) insulation from the cable for a length of about 3.5 cm. We thread the end of the cable into a plastic cartridge. We clean the metal "ears" of the plug with a file. The bare aluminum or copper braid is divided into two equal parts, with the formation of two "whiskers" (you will solder them). Do not forget to expose the center conductor from the protective layer. Cleaned, it is placed in the plug. Now the soldering iron comes into play. You need to solder the braid to the petals of the connector, and then the cable core in the central channel of the plug.

The reliability of the contact at the place of soldering can be verified by trying to tear it off, for example, with a knife. If you managed to break the solder, then the soldering was unsuccessful, and you need to arm yourself with a file again. The same applies to solder drips - they need to be removed.

After all the manipulations, combine the plastic sleeve with the metal base (a special lock will work).

If the mesh braid protrudes beyond the edges of the connector, then, for aesthetic and safety reasons, it should be cut off. Braid wires can easily penetrate the skin and, breaking off at the level of its surface, are difficult to remove and cause stabbing pain.

Where to insert the antenna cable on the TV

Before buying a plug or adapter for an antenna cable, you should carefully examine the socket on the TV and remember how it looks. Not to confuse the antenna connector with the rest of the inputs, its designation will help: “ANT IN”, “RF”, “Antenna / RF IN”.

If there is very little space behind the TV, it is worth considering an angled plug. If the connector lies deep in the TV case, then it is better to buy a plug without "bells and whistles", as "thin" as possible.

Which TV plug is better and more reliable

At present, the entire connection technology in television installations is based on F-type connectors. With their help, terrestrial, satellite, cable TV installations, and collective ones are created. The variety of F-connectors is huge - from cheap Chinese crimp, compression and self-crimp plugs to "fast" connectors like CaP. In addition, there are straight and angled versions of the connector.

Here is what speaks in favor of this type of cable connection:

• F-connectors are inexpensive;
• installation can only be done with a knife;
• F-connectors give good contact, noise-resistant and universal;
• maintain reception quality.

Russia is actively moving from analog to digital TV. In principle, this is a completely natural process, since the improved signal transmission format allows you to broadcast the highest quality image. All users are concerned about how to connect digital television.

To begin with, this is an accessible standard, not some privileged feature. Note that today each user has access to about 20 free TV channels, depending on the region.

You need to set up digital TV broadcasting at least because you can watch your favorite channels with clear sound and high-quality images. However, first you have to purchase special equipment.

Channels in digital format are broadcast in packages, which are commonly called multiplexes. At this stage, Russian subscribers are offered 2 free multiplexes, each of which has 10 TV channels.

Benefits of Digital TV

Digital TV is a new signal transmission technology that delivers high quality images and pure sound. Connection digital television opens up completely new opportunities for each user, for example, you can watch broadcasts in HD quality. Naturally, analog TV cannot boast of this.

The concept of the technology under consideration is as simple and clear as possible. Picture and sound are transmitted on radio waves as separate streams. In general, this process resembles the connection between a computer and the Internet. Therefore, digital TV can be compared with watching YouTube from a computer.

In addition, precisely due to this algorithm providers will be able to send much more TV and radio programs. A large number of channels are far from the only advantage. The functionality, in principle, has noticeably expanded, interactive TV has appeared. You can pause your favorite show or record to your hard drive.

Main advantages new technology TV signal transmission:

• high image quality;
• clear and rich sound;
• broadcasting of medical content in HD format;
• available different language versions of one program;
• blocking pre-selected TV channels.

Connecting a digital TV antenna is worth at least because all modern TV models are designed to play content in HD format. Ordinary analog air is simply not capable of transmitting such data. At a minimum, there are enough free multiplexes. Therefore, you do not have to pay to watch your favorite channels.

What you need to connect digital TV

In order to connect the "digit" to your TV and fully use the main advantages of this format, you first need to spend a certain amount Money for the purchase of appropriate equipment.

The situation will be noticeably simplified if you use a TV with a built-in T2 adapter. As a rule, only modern models are equipped with them. In other cases, you have to additionally buy a receiver, and sometimes change the antenna. In order for all elements to work correctly, they must be connected with a cable.

How is digital television connected through a TV? Where to begin? If you live in a multi-storey building and are connected to a collective television antenna, then you first need to find out if it is adapted to receive a digital signal.

Ask your neighbors - it is likely that they are already enjoying all the main advantages of the “numbers”. In this case, the collective antenna is suitable, and you do not have to change it. It remains only to purchase a set-top box and set up a home television network.

What is needed to connect the "digit"? We list in detail the necessary equipment.

Antenna

If you live near a television tower, then you can receive a signal using the most ordinary room decimeter antenna. Otherwise, you will have to change the wave receiver, give preference to a simple directional model. In addition, it is very important to correctly position the antenna on the tower for high-quality DVB-T2 reception.

Amplifier

In the process of choosing an antenna, questions will arise regarding the appropriateness of signal amplification. If you have previously used amplifiers, then you should not refuse such a practice even if you connect the “numbers”. A good amplifier will provide high-quality signal reception even in places that are extremely far from television towers.

Broadband antennas amplify not only the power of the T2 band, but also all radio waves with similar frequencies - sometimes this prevents the desired signal from being decoded. Therefore, if the reception is good, then the amplifier should not be used. Sometimes his connection is harmful, not beneficial.

When connected digital channels many people buy amplifiers with a 12V power supply. However, according to T2 standards, latest models receivers give out a voltage of 5 V. Therefore, in active antennas that are designed for the DVB-T2 format, the amplifiers operate on a voltage of 5 V when directly connected to the set-top box. This is a budget and practical solution. First of all, an additional power source is eliminated.

Tuner

The set of equipment for digital TV must necessarily include a receiver. This device performs the functions of a decoder. Tuners are characterized by maximum practicality and ease of operation. Basic buttons are located on the front panel, but the main tool for controlling the device is a remote control.

The decoder functions correctly together with the TV. In order to qualitatively set up the broadcasting of channels and connect the device, it is necessary that the decoder be equipped with an HDMI interface and support the HD format. Otherwise, even HD channels will be no different from standard analog quality.

Cables

Connecting equipment for viewing digital TV is carried out using a cable, so it is also an integral element of the whole structure. Receivers are connected to old TVs via an RCA tulip or Scart input, and to modern TVs via an HDMI interface. Therefore, in any case, you will need a cord with the appropriate connectors.

To get a high-quality image with high resolution, you need to connect the TV to the set-top box via HDMI. RCA and Scart connectors do not support HD format, therefore, the picture will be the same as with analog TV. In some situations HDMI cord is included in the basic package of the tuner, but still more often it has to be bought separately.

The antenna is connected to the receiver using a coaxial cable, again, you can find it in absolutely any store. We connect the coaxial cable through one of the available connectors: RFIN, RF-In, RF imput. Fasten the plug well at the end of the wire, the quality of the broadcast image depends on it.

Connecting digital terrestrial television

If you use an old TV, then you will need a special receiver to connect the "numbers". The new models are equipped with T2 adapters, we have already talked about this earlier, therefore, you do not need to buy additional equipment for them. Be sure to check if the built-in module works according to the MPEG-4 standard, which is valid in Russia.

To learn how to connect a digital terrestrial television, you first need to select a signal reception method.

1. Connecting the "numbers" through the most common common antenna, which is installed on the roof of your house or in the entrance.
2. You can also watch TsETV by connecting cable TV. This service provided by many providers.

We will first consider the first option, since it is more practical and less expensive. If you do not have a common antenna, proceed to the next step in choosing and buying an antenna.

Digital terrestrial television allows you to set up about 20 free channels - 2 multiplexes. Of course, the cable TV provider will offer much more, but you will have to pay for it.

It is likely that a third multiplex will appear soon, which will also be free, but for now this question is up in the air. Firstly, the Russian infrastructure is not designed for a very large broadcast range. Secondly, there are certain problems associated with the lack of frequencies. Experts believe that 2018 will be a turning point in the issue of abandoning analog television. Accordingly, the number of free channels will be finally fixed.

Now consider the intricacies of the transition from analog to digital television. Conventionally, the process can be divided into 5 stages, consider each of them.

Antenna selection and installation

If you plan to independently set up a connection to digital television, then you need to start with the choice of an antenna. First, remember that there is no single universal solution, so the model should be bought based on the individual characteristics of the house / apartment. Secondly, you can always install an antenna that can receive a signal even in remote regions.

The most attractive option is an ordinary indoor antenna, but as practice shows, its power is not enough. Predominantly, interference occurs, which will appear every time trucks pass near the house.

Even if a powerful integrated amplifier is used, it will be extremely difficult to achieve high-quality reception, since obstacles dampen the waves. Indoor antennas can only be used if you are in an ideal location - near the tower, and the window is directed to the repeater.

External signal reception is a more efficient solution, especially compared to an indoor antenna. The wave range passes through the walls of the house, but the signal quality suffers significantly because of this. An external antenna will provide a strong signal.

Which antenna is better to choose: active or passive? To answer this question, you need to consider how far it is from the DVB-T2 tuner. Practice shows that a passive model is often enough. It is not equipped with an auxiliary amplifier, although the cable length is very short. Active antennas are equipped with a built-in signal amplifier.

Determination of the location of the television tower

To find the nearest tower, you need to study the map of digital TV in Russia. Add the name of your locality through the search menu, and then estimate the distance and direction to the nearest signal transmitter. Naturally, you also need to take into account the parameters of broadcasting.

Setting the equipment according to signal reception quality

Reception zone - maintaining a high quality of signal transmission, regardless of third-party factors:

• weather;
• solar Activity;
• season;
• temperature;
• air humidity level;
• Times of Day.

If the transmitter is in the line of sight, then reliable signal reception is guaranteed. The main thing is to direct the antenna correctly.

As for the remote zone from the TV tower, there are often problems with signal transmission. Outside the sure zone, radio waves are obscured by the earth's surface, so it is difficult to tune in to a TV broadcast.

According to official data, the problem is solved by the correct placement of transmitters, in other words, new towers are being built. In any case, in an area far from the transmitter, the quality of the signal will depend on the weather conditions. Therefore, it is so important to fix the antenna in the right direction and fix it securely.

To receive signals over a long distance with minimal loss of quality, use large antennas that differ from analogues in a more complicated design. Subscribers located in a remote area must select the optimal equipment design, guided by the maximum gain. At the same time, the dimensions of the structure should remain minimal. Usually the problem is solved by using directed models.

Setting up antenna and television equipment

To complete the digital connection, you first need to connect the equipment with a special cable. After that, you can connect the TV and receiver to the mains. Position the antenna away from the nearest transmitter.

The process of setting up the decoder is simplified as much as possible, so there will absolutely no problems with connection or control. On average, all work takes about half an hour, for a correct connection, follow the recommendations prescribed in the instructions.

After the first launch, the “Autoinstall” assistant menu will open, here the installation of the most important parameters that determine the operation of the receiver. The labeled buttons on the remote control will help you step by step setup equipment.

Once the antenna is pointed and connected, and the receiver is set up, you need to make sure that all cables have been connected correctly. Then turn on the TV.

Channel search (automatic or manual)

Most users prefer to tune channels automatically. To do this, open the menu and go to the "Auto Search" section. Do not turn on the equipment until the scan is complete. If channels are not found, then the receiver is not receiving a signal from the antenna.

Try moving the antenna, and then start the auto scan process again. Check the signal quality by changing the position of the antenna. Do this until you have tuned the TV channels of the desired multiplex.

As for alternatives, it's worth returning to the main menu, and then going to the "manual search" section. On some equipment models given function may be called a little differently. A list will be displayed on the TV screen, in which you need to manually enter data on television broadcasting, frequency, then you must confirm the search. Properly performed manual tuning - the presence of 20 free channels in excellent quality.

Digital cable TV connection

To connect cable TV in the "figure", you should use a universal receiver. In some situations, users buy a digital cable box. Such devices are equipped with an additional PCMCIA connector for connecting the CAM module, which contains a pay TV access card. Naturally, one must first choose one of tariff plans offered by the provider.

Many modern smart TVs are already equipped with a built-in PCMCIA slot, so there is no need to purchase additional equipment.

To correctly read the CAM board, it is desirable to use a high-quality card reader, however, devices of this type are used much less often, since users often prefer hybrid digital receivers.

To connect digital TV to your TV, just follow the instructions from the provider. As for channel settings, you can use the recommendations given earlier. Mostly receivers work on a similar principle, problems should not arise. The only difference is that when connecting digital cable TV, it is not the RF wire that is used, but the provider's cord.

Connecting two or more TVs to one set-top box

The ideal option is to connect one TV to one set-top box. Therefore, the best solution would be to purchase separate receivers for TV devices. Naturally, this will not be the most budgetary way to solve the problem. The user connects a cable to a splitter, and then from each input it goes to separate receivers. The connection scheme is as simple and clear as possible.

If you wish, you can connect a second TV to one set-top box, for this you just need to use all available interfaces. For example, through HDMI we connect the first device, and with the help of "tulips" the second.

Connecting digital TV according to this principle is not the most the best way because both TVs will receive the same signal. In other words, the picture is synchronized, you cannot watch different TV channels at the same time.

An additional solution to the problem is to purchase an RF modulator that will feed individual decoded signals to the TVs. However, the cost of such a device is much higher than the price of a conventional receiver.

Note.

Television antennas have been known for a very long time. They appeared at the same time as TV signal receivers and have undergone significant changes since then. Currently, these devices have improved so much that they can receive not only analog, but also digital signals. According to their purpose, they are indoor, outdoor and hybrid, which simultaneously combine the qualities of the first two types.

An indoor antenna with an amplifier, which provides high-quality image and sound reception, is widely popular among the population. Choice given devices is carried out based on the operating conditions and the ability to receive a certain frequency range.

The main types of television antennas

To the main differences of modern indoor antennas include them design features, as well as the range of signal reception.

These devices are divided into the following types:

• Meter antennas are considered the simplest. Their design consists of a platform with antennae, providing signal reception at a distance of no more than 1 meter. Such devices are becoming less and less popular as they receive only about 5 channels.
• Decimeter or loop antennas structurally include a cable connected to a TV, as well as a platform and an open loop. Designed for digital television of a certain format. The signal reception range is up to 30 km.
• Hybrid antennas are capable of receiving meter and decimeter waves. If necessary, you can switch the wave ranges.
• Passive indoor antennas can simply receive the signal, but not amplify it. These devices are used only in the immediate vicinity of the television tower.
• The most modern and advanced device is an active indoor antenna with an amplifier. They receive signals from long distances and distribute them among several television receivers.

Each indoor antenna is designed to be installed indoors to reliably receive television signals in accessible areas. These are not outdoor appliances, characterized by increased power. Therefore, when choosing a device, one should take into account its remoteness from the repeater, the power of the transmitter, as well as the density of buildings with multi-storey buildings. You should also take into account the location of the floor, landscape features, the presence of domestic and industrial interference. The quality of the signal directly depends on the distance between the antenna and the transmitting station. .

What to do if the indoor antenna does not work well

Often there are situations when the receiving device, despite right choice and specifications does not perform its function well. However, this state of affairs does not always mean the inefficiency of the chosen design. Therefore, do not rush and buy new model. It is recommended to do several simple actions, which will correct the situation and improve the quality of the received signal.

First of all, you need to try to adjust the height of the so-called telescopic whiskers. In some cases, changing the height of the entire antenna helps a lot. The fact is that some types of interference do not pass the signal at one level or another. Quite often, this measure can significantly improve the quality of the T-signal.

Sometimes serious interference is created by metal-plastic structures of modern windows. Therefore, the antenna should be deprived of direct contact with metal parts, fixing it on glass or on a separate stand. Good results gives a change in the angle of rotation of moving parts or the entire device. The antenna, located at an optimal angle to the TV signal source, contributes to a noticeable improvement in reception. Such changes should be slow and smooth, since even a slight shift can affect the quality of reception.

If all the measures taken did not give the desired results, and natural factors cannot be overcome, you can try to use antennas with an amplifier more high power. In the absence of the desired effect, an outdoor television antenna with a higher power will help solve the problem.

Setup and connection

In enclosed spaces, radio waves propagate differently than in open spaces. In rooms there is a more pronounced interference of the magnetic field. Therefore, setting up indoor antennas requires certain knowledge, time and patience.

As a rule, receiving devices are installed either near the TV, or on it. The quality of the TV signal will be better if the antenna is placed near a balcony or window facing the repeater. The most suitable location can be determined by moving the device to different places in the room. In the end, the place where the image will be of the highest quality is selected. Movements must be carried out not only in the horizontal, but also in the vertical direction.

Having decided on the place, it is necessary to adjust the length of the telescopic pins. They need to be advanced slowly, gradually, until a high-quality image is obtained on the channels of the meter range. Sometimes the pins can be extended to different lengths, thus increasing the number and quality of adjustments. The angle of divergence between them is also selected empirically, according to the state of the received signal.

In order to tune UHF channels for digital television, it is necessary to move the entire antenna body in a horizontal plane until a good, high-quality image appears on the TV screen. If the television antenna is equipped with a gain control, you must use it. In addition, the position of the device may change in space during channel switching. These steps allow you to further adjust the image quality. Active television antennas switched on via a power supply connected to the network. The presence of power is indicated by a burning LED located on the unit body.

The antenna itself does not require any technical manipulations. These devices are sold with a cable connected and a connector for connecting to a TV, that is, they are initially fully functional.

How to choose a TV antenna

Indoor antennas fully perform their functions, subject to all the conditions listed earlier. According to its capabilities, each such modern device no worse than an external antenna, and often even surpass them.

All receivers for internal use are divided into two main groups. They can be rod, working with meter waves, and frame - designed to receive decimeter waves. Each of them can have an active variety, which involves connecting through an adapter to electrical network. It is possible to determine which of these devices are the best only in specific operating conditions.

The first option is the most widely used. Such antennas have a design consisting of two rectilinear telescopic antennae mounted on a common stand. The total length of the rods is approximately one meter, and they are connected to the TV through. Inside the stand is a special device that ensures the quality of the received signal.

Loop antennas are made in the form of an open annular metal frame, to which a connecting cable is connected. At present, a broadband indoor antenna with an amplifier, also known as a log-periodic antenna, has appeared.

These devices provide better reception of the TV signal of the vast majority of transmitting stations, digital transmission is also well received. They are chosen in cases where the frequency of reception is not known in advance, as well as in the perspective of the emergence of new channels. The universal design includes not only a telescopic mustache, but also a frame. In fact, two devices are connected in one case. This is currently the best design capable of working in a wide variety of conditions.

Amplifier indoor antennas: pros and cons

For most people, satellite and cable television have become the main ways to watch television. The first option is considered very expensive, and the second one cannot always be used in country houses and cottages due to their remoteness.

In addition, these devices often work intermittently, so in many cases indoor antennas for a TV with an amplifier are the most suitable option. They are used exclusively inside buildings and are connected to the TV via a regular coaxial cable, they are mainly used where an outdoor antenna cannot be installed for technical reasons.

These devices are quite reliable, have a simple design and are relatively inexpensive. Last Advantage it is very important when choosing an antenna for giving, used from time to time. Therefore, it is more economical to purchase a budget device for 400-600 rubles than expensive satellite equipment.

A fairly powerful indoor antenna has a compact size and fits seamlessly into the interiors of the premises. Black, gray and other neutral colors of devices do not stand out at all from the general background. Amplified antennas are easy to install, just enough with a cable. Tune home tv easy, because each model comes with detailed instructions for operation.

The disadvantages of indoor antennas are primarily related to customization signals and a small number of received channels. Good quality reception is provided only in the vicinity of the repeater, and the resulting image in many cases is far from ideal.
