Antenna amplifier for 2 TVs. How to connect a second TV? It couldn't be easier! Connection via connectors

Almost everyone knows for sure that television replaces us, or rather implements one of the opportunities to have fun. Let's say more, it is still quite competitive in relation to the Internet, which has become our everything. The only thing is that even if you have several TVs in the house, you can watch only one program on each of them. If someone wants to watch something different or in another place, then there is a need to connect two or more televisions to one receiver. It is this option, when you need to connect two or more TVs to the receiver, that we will talk about in our article.

Options for connecting 2 TVs to the receiver(s)

If we talk about connection options, then there are essentially two of them. No, of course, you can come up with a great many variations, but so that they are fundamentally different from each other, there are only two.
The first is when two TVs are connected to one receiver. If I can say so, they are connected in parallel, that is, the TVs show virtually the same thing.
Another option is when we have one antenna, two receivers and two TVs. That is, the signal goes to receivers - receivers, is divided to the antenna, and then decrypted by any receiver for each TV. As a result, each TV shows its own programs, independently of the other.
So, now let’s start analyzing both options according to the schedule, with their own connection features.

Connecting 2 TVs to one receiver (same signal source)

The first option, as we would say, is simpler. It is for those cases when you need to watch the same thing. That is, one video signal will be broadcast to two TVs. These are options when you can watch the same thing in different rooms. For example, when in one room the TV has already been turned off, and in another they are still watching TV. The only problem is that you still have to switch programs where the receiver is directly installed. This is of course inconvenient.
So, the connection diagram in this case will be simple. Signal from satellite dish(antenna) goes to the receiver, where it is decrypted and then sent to the TV. In this case, it can come through RF OUT or through tulip (RCA) plugs. Just if the receiver supports the ability to output video and audio signals in various ways, you can take advantage of this. For one TV, take the signal from RF OUT, and for the second from “tulips” or Scart. In order for you to better understand what and how, we will provide several connection diagrams and provide explanations for them.
The first connection option is when one of the TVs is connected via an RF socket, that is, actually via an RF cable. We talked about installing plugs on such an antenna cable in one of our articles. But the second signal is taken from Scart.

The following option is when we want to divide the signal into 2 TVs only with the support of an RF modulator. In this case, the modulator is the same as a tee for a power outlet. Here you can connect at least two, at least 4 TVs. Or rather, as many connections as the modulator allows.

Well, the third option, quite alive for modern receivers, is when Scart or RCA and HDMI output are used. In this case, you will not even need to purchase any modulators or splitters. The ability to connect the receiver using various methods already actually realizes the receiver’s ability to work with 2 various TVs. All you need here are the appropriate wires.

I would like to say the following again about all these connection methods. Firstly, the signal to each of the TVs will arrive alone and the same, which is not suitable for some.
Secondly, the cable from the receiver to the distant TV should not exceed a length of 15 meters. Otherwise, there will be so much interference that you won’t be able to watch the video comfortably.

Connecting 2 TVs to two receivers (two signal keys)

The second option involves connecting two receivers to two TVs. This option, in our opinion, deserves more attention, since, so to speak, it is complete. Here, each of the receivers receives a signal from the dish, and then decrypts and sends the signal for processing by the TV. The advantages here are obvious. Can be watched on different TVs at the same time different programs. Program switching is carried out directly from the receiver installed next to the TV. There is no need to run around and switch programs somewhere and by someone. Well, the cables for switching between the receiver and the TV will require a much shorter length than in the option above.
The only negative is that this option is quite expensive. Let's analyze the connection diagrams according to this case.
There are two options here, when the receivers are of equal value, that is, if it is fashionable to say so, self-sufficient. Each of them can work without the other and the case is when one receiver receives an RF signal, and then processes it and, through digital signal transmission, transmits it to 2 receivers.
First, about the first option.
Here the RF signal must be divided before it arrives at each of the receivers...

...or do this. The signal arrives at one receiver and goes on to the next one...

The point here is simple. Each of the receivers receives a similar signal and works with it in isolation. In principle, it turns out like one receiver, one TV, the connection diagram is the same. Is it really possible that there is only one antenna for two?
Another option for connecting two TVs and two receivers was implemented by the Tricolor company. In this case, the GS e501 and GS c591 receivers work as follows.

The main receiver receives the signal, receives it on the receiver, or rather even two, and decrypts it. Next, the digital signal is transmitted to the second receiver. In this case, the other receiver is deprived of a receiver, which allows the manufacturer to save somewhat on the cost of such a connection, which means a negligible reduction in price for the user.

To summarize...

So, if we summarize the topic of connecting two TVs to one and two receivers, then we can say that each of the options is possible. The only thing here is to decide what suits you. After all, this condition itself will become the starting point for the implementation of connection diagrams. It should be noted that in addition to the connection diagram, the receivers are poorly configured. Here it is necessary that the signal from the antenna arrives at the proper level, that is, the circuit is not a panacea for solving the problem. It does not relieve you of the need to configure receivers and this must be considered.

Several TVs in one apartment are not at all surprising these days, but there is usually only one antenna for them.

In such a situation, a very appropriate idea appears, which is to connect televisions to one antenna.

But it will not be possible to make a high-quality connection without a signal divider or other device.

Cable splitter

This device matches TVs and antennas. The splitter allows you to send a high-quality signal that does not fade and does not receive extraneous interference.

In the standard version of splitters, you get only two outputs, but in more expensive models there may be more.

It is worth noting that when purchasing such a device, you need to pay attention to the signal range that this device can miss. More detailed information can be found in the instructions for the device.

The splitter, or as it was popularly called CRAB, is enclosed in a very durable and interference-resistant housing.

The body is not even susceptible to corrosion, and in comparison with strength, it is not much inferior to steel. On the outside you can see the antenna input and TV outputs.

The transformer-type circuit looks like an enamel-coated wire with a cross-section of 0.4 millimeters. It is threaded into ferrite-type rings or tubes. A lid is attached over the entire structure, which creates a tight seal.

Number of TVs

Before you start connecting, decide on the number of TVs. If you decide to connect three TVs at once, the operation scheme will be different than with one TV:

With each addition of a new TV device, the signal becomes less powerful for other TVs, but it is distributed evenly among all.

But this problem is easily solved by an amplifier. Nowadays, stores are full of these devices, and the quality of the signal received from them in the rarest cases is a little disappointing.

Splitter circuit

If you purchased a splitter in a store, then most likely all you have to do is insert the cords into the sockets and everything is ready, but it also happens that you need to do everything from scratch.

Installation instructions from scratch:

First of all, you will need a coaxial cable, the length of which will be approximately 10 - 15 meters, depending on the distance of your TVs from the antenna.

Insert all the plugs into the appropriate sockets. Next, you can connect the TV to the network and install channels. But if the signal quality on one of the TVs is low, you will need to crimp the cable again or look for ways to get interference.

Strengthening the signal

Satellite TV users often complain that when they add television equipment, the signal loses its stability and quality.

But this is a very justified dissatisfaction, because the splitter does not amplify the signal, but divides it by power into active sockets.

Once you install an amplifier, this problem will go away forever. But it’s best to do this near the TV.

In cases with interference, you can get by with ferrite rings, which can be easily purchased in a store or found on old microcircuits.

You can install the rings in any convenient place, the main thing is that they fulfill their purpose. These mini interference protectors are found even on the most modern cables.

Laptops, chargers, headphones, etc., they are all equipped with such rings. Some create protection from the cables themselves for equipment, and some are used as signal preservation.

Simply put, ferrite beads work both ways. You should not neglect them even in cases when your equipment is working properly. The fact is that even the smallest interference can become a real problem in the future, because it can cause some of the elements of the equipment to heat up.

After some time, the heated area may finally fail and the signal quality will be lost.

But if you install rings in all weakly protected or very high-voltage places, then long-term problems can be avoided.

You should not remove the rings from the cable, even if you think that this cable is completely harmless to your equipment.

Photos of examples of connecting several TVs to one antenna

Hello!

In your question, you did not indicate how to connect a group of televisions (four pieces) to one antenna. And this is very important, because the strength of the received TV signal depends on this. There may be three options here. The simplest one is to connect the antenna cables coming from the TVs to each other. However, this method greatly weakens the signal and can contribute to the appearance of interference in the form of a “grid” due to the mutual influence of TV devices on each other. Therefore, you can often find two other methods of connecting several television receivers to one antenna.

Using passive splitters

These are devices that are small boxes with input and output contacts for connecting a TV and antenna. Below in the photo is such a device designed just for 4 TVs.

The part can be purchased in the store household appliances or electronics

But the use of these products is advisable only if the signal is strong enough (for example, if you live near a TV tower) or when using cable television. This is due to the fact that when connecting two TVs, the signal is attenuated by 2 times, and three – by 3, etc. It is also worth remembering that poor cables may be the reason for poor reception quality. Here you need to look at:

resistance (must be 75 ohms);
signal attenuation (indicated in dB, the lower the value, the better);
frequency range (up to 1 kHz is enough).

If the cables are normal, but the signal is excessively weak, then it makes sense to use other devices, which are described below.

Active splitters

There are two types of these products: with separate power and its supply via an antenna cable.

The second option is most widespread. What is its essence? Here the device is connected to several TVs, while power is supplied to the active splitter from a voltage source that can be installed next to one of the TVs. In this case, the signal level on all television receivers will be the same and will be 1.1-1.3 of the input. In the photo below you see that the antenna cable is connected directly to the power supply unit (PSU): the signal is then distributed through a splitter.

Typical connection diagram

Power can also be supplied separately from the antenna cable, as shown in the figure.

The choice of connection diagram remains with the user

There is an important point here: the power supply can be regular or adjustable. In the latter case, it is possible to adjust the level of the received signal. The fact is that if it is excessively strong, it can lead to distortion of the picture on the TV (a similar situation is typical for antennas located not far from the repeater tower).

Very often, a second TV appears in one family. In this case, there is only one antenna. The question arises: how to connect two TVs to one antenna? There are ways to use one antenna on two or more TVs.

To connect, you will need several parts:

two-output splitter (splitter). This is a device that allows you to divide the signal from the antenna into two or more streams. It has an input on one side and two or more outputs on the other - for connecting television receivers.

5 connectors corresponding to the splitter;
2 adapter plugs;

We will try to talk about the connection in such a way that even someone who does not understand radio engineering at all can cope with the task. This is done step by step like this:

Selecting the details. The first thing you need to do is buy a splitter. They come in a variety of varieties, including those that require soldering and those that do not. If you know how to solder, then it is better to take those that involve soldering. This connection is always more reliable than any other, it produces less signal loss and preserves its quality.

If you do not have soldering skills, then you need to choose an appropriate splitter, as well as one suitable for a specific type of cable. A win-win option would be a splitter with built-in sockets for coaxial cables.

Having chosen a splitter, select the appropriate connectors. F-connectors are now very popular due to the fact that they are reliable and easy to install.

Choosing a location for the splitter. It is optimal to position the device so that the antenna cable can easily reach it and, if possible, have the shortest distance to both TVs.
We cut the existing antenna cable. It is necessary to cut so that the cable can freely reach the splitter. The old plug is cut off along with a piece of cable.
Cable cutting and F-connector installation.

For those who know how to solder, there is no point in telling them how to cut a cable and solder it to a splitter - they know it themselves. What follows is written for the average user who is not familiar with the radio business.

So, we cut the cut end of the wire as shown in the figure: we strip the edge and wrap the braid. The middle core insulator should protrude slightly, and the middle core itself should protrude by at least 5 mm. The tool for removing insulation from a coaxial cable at home is an ordinary kitchen knife.

Install the F-connector. It is also called wrap-on because the connector is wound onto a soft wire. The connector for connecting the cable and splitter is ready.

We cut off two pieces of wire so that the length is enough for each TV.
We mount F-connectors in the same way to connect television cables and splitter outputs. We do the same at the other ends of the cables.

As a result, we have all five connectors used, including:

one from the antenna, to enter the splitter;
two televisions, for exiting from it;
two televisions free.

We connect the connectors to the splitter.

We connect two free connectors with adapters. An adapter is a device with an F-connector attached at one end and a coaxial plug at the other for connecting to television receivers. Typically this device is generally referred to as a plug.
We turn on the television receivers. Let's check how both receivers work. If everything is done correctly, the image should be normal. Now you can easily enjoy an excellent picture on two receivers at once, without interfering with each other.

Using the diagram below you can see the path along which you need to connect 2 TVs to one antenna:

How to connect two TVs. Connecting a TV cable

Dear visitors!!!

Many of us need to connect two televisions to one television cable. While going about our business in the kitchen, for example, or relaxing in the hall, we can watch one or another television channel and keep abreast of all events happening in the world. This opportunity is provided to us when connecting a television cable through a television signal divider.

TV signal divider

Connecting two TVs to one cable is done through a television signal divider. When purchasing a signal divider, a diagram of such a connection is provided on the case itself. So, how to connect two TVs to one cable from one antenna. Let's start with the television cable itself.

Connecting a TV cable

You must first decide where you will cut the television cable for further connection of two television cables to the television signal divider. You will have one common television cable that receives the signal from the television antenna, connected to the television signal divider socket.

How to connect the plug-to-television cable

In addition, it is necessary to have another TV plug available. To solder a television plug, you need:

remove a small part of the cable insulation;
unwind the outer braid of the cable;
twist the braid and etch with soldering flux;
Solder the outer braid to the outer contact of the plug.

The internal wire of the television cable, after it has been moistened with soldering flux, is soldered to the internal contact of the plug.

The connection of television cables to a television signal divider is carried out with the initial removal of a section of cable insulation.

Now, let's take a look at the diagram for connecting two TVs to one antenna.

Connection diagram for two TVs to one antenna

Connections from one common TV cable are shown here:

for two TVs;
for three TVs.

The signal from the television antenna is distributed through a TV signal divider and is supplied via cable to the TV socket.

You should not focus your attention on connecting through a television signal divider. The second connection option looks like it's through a junction box.

Junction box

In this embodiment, the method of connecting two TVs is clearly shown, where the cable wires can be connected in a junction box. The connected contacts of the signal wires of the television cable are etched and soldered with soldering tin. Connecting two television cables to a common cable is parallel. As you have seen, there is nothing complicated here.

That's all for now. Follow the section.

How to connect two TVs to one antenna: work procedure

Almost every average family has a second TV: in the kitchen, in the bedroom, and sometimes in the hallway. Therefore, for many, the question of how to connect two TVs to one antenna is quite acute. There are quite a few ways, but we will focus on the simplest and at the same time effective options.

So, let's figure out how to connect two TVs to one antenna, what tools are needed for this, and also outline the main stages of this process.

What you will need

During the connection process we will need several parts. The tools will be pliers, side cutters and a regular kitchen knife.

First of all, we need a TV splitter, or splitter. This device is capable of dividing the signal from the antenna into several streams (in our case, two). That is, on one side there is an input, and on the other there are several outputs for connecting to the receiver.

Next, we will need five connectors that match the diameter of the outputs on the splitter, as well as two adapter plugs. Choose the antenna cable at your own discretion, but it is better to stick with even more expensive, but proven options - RG-6 or domestic RK-75.

It is also worth considering that when purchasing a splitter, be sure to check the number of outputs. For example, three-way models are designed to connect exactly three TVs, but not two. If for some reason you have a splitter for three receivers at hand, then the unnecessary output can be plugged with a special ballistic resistor with a resistance of 75 Ohms. Be sure to pay special attention to this point before connecting two TVs to one antenna.

In principle, the connection process itself is simple, and any user can handle it, even those who have never heard of radio technology. For clarity, we will divide the entire process into separate stages.

Choosing a TV splitter

First you need to buy a splitter. On store shelves you can find a wide range of models from different manufacturers. A simple rule applies here: the more expensive, the better. But there is one more important point that is worth paying attention to before connecting two TVs to one antenna. We are talking about soldering. If you have skills in working with a soldering iron, then it is better to give preference to models with soldering. Such splitters, and this connection in particular, are always more reliable; they involve noticeably less signal loss while maintaining quality.

If a soldering iron is something incomprehensible for you, then you can take a regular splitter, but again taking into account the type of cable you have - or vice versa. The best option is a splitter with standard connectors for coaxial wires (antenna cable type RG-6/RK-75). After you decide on a splitter, you need to select the appropriate connectors. The most popular is the convenient, reliable and easy-to-install F-interface (adapter-wrap).

Also, special attention should be paid to the location of the splitter. The best option The distance from the splitter to both TVs is considered to be approximately equal. It is important that the cable for the antenna is not stretched and does not twist, that is, there is no need to try to stretch it due to lack of footage, or, conversely, twist it. Calculate the distance from the splitter to the TVs in advance and cut off the excess.

Cable preparation

The cable must be cut so that it can easily reach the splitter. As a rule, the old plug is cut off along with a piece of wire. Then you need to cut the cable for installation in the F-connector.

First, we clean the edges, that is, we cut the wrapper to the braid (about 15 mm from the edge) and bend the edges. The insulating “coat” on the cable should protrude slightly, and the core end itself should protrude by at least 4-7 mm. The entire procedure for preparing the cable for the plug adapter can be performed using a kitchen knife and side cutters.

Features of the procedure

It is also important to know that the cable braid should not touch the central core in any way. Such an error can result in partial or complete loss of the signal. Similar problems most often arise with SAT 703B and DG-113 cables, where each layer is very thin.

Next, we mount the F-connector on the cable. It got its name “twisting” due to a specific installation where the plug is simply screwed onto the wire. A similar procedure must be done on all cables - and in the end you will get five connectors: one from the antenna, two for output and two for input.

Connection

We connect the cables to the splitter in the required order. Do not over-tighten the F-connector, as this may cause the main core to fall out of the adapter. Most users leave the splitter as is, that is, hanging somewhere on the baseboard or under the bedside table. Experts recommend that the splitter be properly secured to avoid ruptures and core loss. If there are children in the house, then this point is mandatory, plus it would be a good idea to hide the splitter under some kind of false panel.

If everything is done correctly, the image on both TVs should be clear and free of interference. Otherwise, specific “snow” may appear due to the loss of part of the signal or no picture at all.

Satellite TV

It often happens that even after proper installation of the splitter, the image quality has noticeably deteriorated. This happens if you connect two TVs to one satellite dish. The problem arises because the splitter takes away part of the signal in any case.

One of the options for solving this problem is to buy a splitter with a built-in signal amplifier. Such devices are noticeably more expensive, but at the same time they are much more efficient than their simple counterparts.

It is also worth clarifying that all splitters with a built-in amplifier have different gain factors. In some cases, a clearly increased signal is as useless as a weak one. Moreover, it can cause even greater picture distortion. This nuance is very often encountered by those who want to connect two TVs to one Tricolor or Rainbow TV antenna. Here you need to seek help from a service specialist from your provider, who can measure the signal level and give advice on choosing a particular splitter with specific numbers.

If we are talking about a regular “Polish” antenna, then to improve the signal you can connect an amplifier with a power supply, which will significantly increase the quality of the image.

To do this, you need to make some changes to the already familiar scheme. It is necessary to remove the F-connector from the entrance to the splitter, then install the plug with the power supply that comes complete with the “Polish” antenna in the free space. After this, an adapter with an antenna socket (“female”) should be mounted at the input and a connector with an amplifier should be connected.

This procedure will increase the gain, where, unlike satellite TV, the maximum value is not so important, so there should not be problems with signal overload.

It would also be worth noting that each subsequent TV significantly reduces the quality of reception. Therefore, in order to comfortably watch your favorite TV shows, it is better not to skimp and purchase an additional antenna instead of “doing magic” with a splitter. This advice is especially relevant if the TV tower is located at a great distance from the receiver.

Your question:

How to connect two TVs to one cable?

Master's answer:

In order to connect several TVs to one cable, you can use several methods. The choice of method depends on the final purpose of the connection.

If you want to connect a couple of TVs to one cable TV wire, then use a splitter designed for this. It is a tee that branches the cable. Connect one end of the splitter to the cable itself, and all the others to your TVs, using suitable wires.

If you have a receiver connected to access satellite television, you will need to buy an additional splitter. The connection depends on which channel you have selected to connect the receiver to your TV. Today you can buy splitters with VGA and DVI ports. Connect it to the cable that comes from the receiver, and then connect the TVs to it. You should know that if you use additional adapters, this will allow you to connect VGA, DVI and HDMI ports. Buy yourself a suitable set of such adapters. But remember that the use of such accessories greatly reduces the signal quality. And also remember that with this connection method, all TVs will show the same channel.

You can use a VGA or DVI port splitter to connect all TVs to one computer video card connector. In this case, the two devices will show the same channel. The most good decision- is to use both types of connection. To do this, connect the cable of a conventional antenna to two TVs in the manner described above. Now connect them to the receiver. This method will help you switch modes from the receiver to the antenna and thereby ensure the ability to select the desired channel. If you want to connect two TVs to one satellite TV, then it is better to choose a company that installs a receiver for an entire entrance or house at once.

In one of the previous articles we talked about how to install and configure a digital terrestrial television antenna. But it should be taken into account that many homes today already have several televisions, for example, in the living room and in the bedroom or in the kitchen. If you use cable television or paid satellite, providers will require an additional fee for a second TV. When using a T2 digital antenna, this feature is available completely free of charge. You just need to properly split the signal into multiple devices.

What is the best way to do this? What additional items will you need to purchase? We will provide answers to these questions and even a little more in today’s material.

First of all, let's look at what additional things you will need to prepare for signal separation and cable routing throughout the apartment.

Connecting to an antenna without an amplifier

The most in a simple way, allowing you to use two TVs with one television antenna, causing a minimum of headaches during setup - when using an antenna without an amplifier. We recommend using it if you live in an area with good reception, as it will protect you from possible over-amplification of the signal.

One of the main conditions when using an antenna with a built-in amplifier is that power must be supplied to the amplifier continuously. If you use the circuit described above, problems will certainly arise, since the power supply will be constantly interrupted. Fortunately, the problem is very easy to solve; you just need to slightly change the connection diagram. How will it change?

Buy a splitter and install it in a convenient place.
Cut and crimp the cables as described above. There is absolutely no difference.
At one end of the cable, directly next to the TV input, you will need to connect an antenna power supply. Taking into account the use of a separator with a power pass (denoted as Power Pass), the voltage will flow to the amplifier on the antenna, ensuring its uninterrupted operation.
If you cannot purchase a splitter with a power supply pass anywhere, you can use a regular one, but the power supply must be carried out before entering the splitter. To do this, you need to use a special adapter, one end of which will be inserted into the input of the divider, and the other, which has an antenna type connector, into the power supply.
