Television is an integral attribute of modern man. It is TV that is the main source of information, the main entertainment and simply a constant companion in the flow of everyday life. However, both first-generation TVs and the most modern models still require the connection of an external antenna for their operation.
At the same time, the cable, even if it is located somewhere along the wall or along the baseboard, is not the best solution, which can ruin the design of the entire apartment. It was to solve this problem that a special television socket was invented.
If you did not know about its existence and for the first time encountered this possibility of laying a cable and connecting a TV, then simply by looking at photos of TV sockets on the Internet, you are unlikely to be able to understand all the intricacies of its design and application.
It’s not that simple, so let’s take a closer look at some of the nuances of this solution, which is especially successful if you value beauty, neatness and are willing to spend a little of your time reading this article. The information presented here will allow you to do everything quickly, without unnecessary problems, and get the expected result from your work.
Main types
There are three types of devices.
Single TV socket, used independently, suitable for laying one wire and installing one TV. There is one entrance and exit here. Minor signal loss may occur (maximum 1.5 dB).
- A pass-through model is required if you need to install two or more TVs. It has one input and two output terminals. The first pin is intended for connection to the next socket, the second – with the cable from the TV.
- Feature: Stable transmission is ensured, however, the flow on the outgoing wires may decrease.
The terminal device terminates the connection in pass-through circuits. Additionally equipped with a 75 Ohm resistance (anti-interference).
By the way. Terminals in sockets can be in the form of clamps or bolts (a hybrid of both is possible). This design simplifies installation.
Types of models
GSM socket is available in different types. For example, there is a standard GSM module that has one connector. And there is also a surge protector, the purpose of which is to connect several devices at once.
The surge protector is represented by a standard extension cord that has several outputs. The principle of operation of the equipment is as follows: first you need to connect a SIM card, having previously disabled the function of constantly asking for a PIN code. Once the card is installed, you need to check it. To do this, you need to call her or send an SMS message. This smart system operates at temperatures down to -20 degrees.
Socket with one connector. In addition to this device, door opening sensors or gas leak indicators, fire safety sensors are sold. When included, this GSM module forms a reliable security system. For example, it can be configured so that the lights in the rooms turn on after a certain time. This will create the impression that someone is present in the house.
Other classifications
Devices vary depending on the signal received:
- TV – terrestrial signal;
- R – reception of radio signals;
- SAT – satellite broadcast.
By the way! Combinations of these options are available for sale (TV+R, TV+SAT, TV+R+SAT). The corresponding designation of TV sockets can be found on their housing.
According to the installation method, sockets are divided:
- Hidden wiring;
- Wall mounting.

Components
Regardless of the type of model, it consists of the following parts:
- Housing (printed circuit board);
- The front part (panel) protects the mechanism from damage (the color can be chosen to match the interior);
- Adder, allows you to connect a satellite and radio transmitter;
- The clamp is used to secure the socket in the mounting box.
A little theory
The radio signal through which an image appears on the screen of a television receiver is of the same nature as household electricity. It is characterized by magnetic field strength, current strength and other parameters. It has a wave character to the same extent, but the frequency of changes in the direction of the current is thousands of times higher. For this reason, it cannot be transmitted through metal conductors made of aluminum or copper - the high-frequency magnetic field displaces the current onto the surface of the conductor, as a result of which its effective cross-section decreases and the electrical resistance increases. In radio engineering, this phenomenon is called the skin effect. For example: at a frequency of 50 Hz (household power supply), the thickness of the skin layer reaches 8.5 mm. And at a frequency of 50 MHz (the first television channel) it is equal to 0.001 mm.
How to connect
There are four schemes for connecting TV sockets.
Single option, used for one TV. In this case, the cable is routed to the point where the TV is placed. A socket box is installed at the end of the wiring, and then a socket is mounted on top.
On a note! It is recommended that the supply of wire in the installation box be up to 30 cm, which will simplify the work.
Star (parallel method), most popular when connecting two or more TVs. A splitter (separator) is necessarily used here; it is mounted at the beginning of the wiring. This element may have a different number of inputs and outputs.
REFERENCE. The splitter distributes the signal evenly across all devices. The equipment receives broadcasts of the same power, without distortion.
- Plus: signal continuity is ensured (damage on one line will not affect the operation of other TVs). Disadvantage: increased wire consumption. Serial connection is used with insertion of feed-through sockets. The wire passes sequentially from one module to another, the connection is completed at the terminal model.
- Advantage: material consumption is reduced.
Flaws:
- Damage in one section will affect the functioning of all subsequent devices;
- The signal strength weakens in some cases.
The mixed scheme contains both pass-through and single modules. They are powered by a separator. This method is chosen if a large number of sockets are provided. The method is used infrequently, but it reduces installation costs and complexity.
On a note! In all cases, an amplifier may be required when more than three TV panels are connected, or a large length of wiring is used. It is placed at the cable entrance to the home. This will ensure broadcast stability. This measure is not relevant if TVs with an automatic gain option are installed.
Pass-through connection
The simplest to implement, and therefore less expensive in all respects, is the pass-through scheme. In this option, each subsequent socket is connected to the previous one, thereby forming a kind of loop, which makes it easy to install and connect several sockets.
In other words, we will get a system that consists of pass-through and terminal TV sockets installed on one cable cable.
The main disadvantage: the pass-through system cannot be used for cable and satellite television. The reason is the signal drop at each subsequent connector (about 10...15 dB), which has a negative effect in all cases, including when laying conventional analogue or digital television antenna networks.
There are a number of other problems, for example, if there is a break somewhere in the middle of the cable, then all subsequent sockets after it will stop working.
In addition, with a sufficiently large number of elements on the cable, on the final connectors, the signal level will generally be insufficient to ensure reliable reception, and the cost of the system will ultimately increase significantly.
Laying methods
This nuance is especially important for apartments with design. It is necessary to lay the lines so that they do not stand out against the surrounding background.
When a house is under construction, this point needs to be thought through in advance. The wire is masked using three methods:
- Decorative finishing treatment;
- Behind the ceiling covering;
- Laying in the wall, followed by applying plaster.
By the way. With the hidden method, appropriate sockets are selected.
If the wiring is external, it is hidden in a plastic box or pipe. The corrugation is fixed to the surface with plastic clips.
If desired and possible, you can hide the line behind the baseboards.

Cable preparation
First of all, determine the type of wire. It should provide minimal signal attenuation. It depends on the installation method:
- Hidden wiring – SAT 703, SAT 50, RG 11, etc., are characterized by good insulation and durability;
- The open method is less demanding; RG 6 or its analogues are suitable.
They start by stripping the cores (with a technical knife or wire cutters). The upper shell is removed to a length of up to 25 mm.
Attention! You need to act carefully so as not to damage the screen.
There are three options for the shielding layer:
- Aluminum layer;
- Copper braid;
- A combination of these materials.
By the way. If the wire diameter is less than 0.7 cm, the screen is turned over the sheath. This measure will ensure tight contact with the device connector.
Smart TV or regular
Essentially, Smart TV is a set of applications built into the TV shell for broadcasting various content from the Internet. Recently, manufacturers have been offering full-fledged Android with Google Play and their own sets of applications as a platform.
The weak point of such solutions is management. Entering queries and moving the cursor using the remote control is long and inconvenient. A solution could be to use a smartphone or tablet as a control element. Check the availability of this option when choosing a model.
However, if you buy a TV without a Smart TV and an Internet connection, you can make it smart later using an external set-top box from Apple or based on Android. Or use an intermediary like Google Chromecast to stream content from your smartphone or computer.
Which option is better? Choose according to your preferences and price. It is quite possible that a separate set-top box will cost much less than a built-in Smart TV in a TV.
The downside of an external set-top box is that it will take up one HDMI port, which could be adapted for something else.
The advantage of external attachments is that they can be changed based on needs. You can also install third-party firmware on them. The speed and frequency of software updates depends on the specific model of the set-top box.
The choice of external set-top box is also determined by your budget. The price of a device, as a rule, directly depends on its capabilities and set of functions.
The only critical criterion is whether your TV supports the resolution. Very cheap set-top boxes may not work well or will not support Full HD resolution at all.

Height
The socket is mounted on the same level as the TV panel. If a wall-mounted TV is installed, the module is placed behind it. This solves two issues at once: aesthetics and safety (inaccessibility for children or pets).
Spectacular performances
The show is hosted by two Timurs - Rodriguez and Batrutdinov. The latter, by the way, was a participant in the second season of “The Mask”.
But the host of the show “Mask” became a contestant in the new program. Vyacheslav Makarov presented the folk song “I’ll go out into the street.” Mark Tishman chose Muslim Magomaev's hit "Nocturne". Yulia Parshuta surprised everyone when she performed the Queen song “Bohemian Rhapsody”. Alisa Mon presented a cover of Kylie Minogue's hit Can't Get You Out Of My Head.
Kirill Turichenko sang Diana Arbenina’s composition “A Second Ago.”
Guest Yusif Eyvazov, invited to the show, recalled how he discovered Turichenko in the “Mask” show. Eyvazov acquired in Kirill not only a good friend, but also a business partner. In March next year, the artists will give a joint concert in Moscow.
Connecting the wire to the socket
In conventional models, you need to remove the cover of the device to expose the connectors. If the contacts are located on the reverse side, dismantling is not required.
The cable core is fixed in the socket. For optimal connection and protection against breakage, part of the braid is fixed with an additional screw.
Connecting TV outlets is a simple task.
- However, you should take into account the amount of equipment used, ensure sufficient signal power and take care of aesthetics.
- By following the recommendations of this article, the homeowner will be able to create a reliable TV connection scheme with reliable reception and will not encounter technical problems in the future.
