When a second television panel appears in the house, the question arises - how to connect two televisions to one antenna. This is quite easy to do. If necessary, you can connect not two, but three or even 4 TVs to a regular antenna, cable television or satellite dish. You just need to know how to do this correctly, and take into account that when the signal is divided into several equal parts, its quality deteriorates.
Possibility of connecting more than one TV to the antenna
When connecting two TVs with T2 tuners to the antenna to watch digital television, you need to be prepared for a loss of image quality. A good signal is divided into two equal parts and in this form is sent to both devices. And if 3 TVs are connected, then the share of each of them only a third of the original signal remains.
Important! Another factor that will affect the final picture on the screen is the length of the cable. The larger it is, the worse the image will be. Therefore, you should make sure that the distance from the TV to the splitter is small.
All this indicates that using one antenna to watch digital TV channels on a pair of devices is only relevant in cases where the signal is initially very good, and its division into two parts will not cause significant image deterioration. Indoor antennas are not suitable for signal multiplication. Several TVs can only be connected to an outdoor antenna(Meridian and others), cable or satellite television (Tricolor, etc.).
How to connect two TVs to an antenna
To split the signal into two television panels, you will need a splitter, five F-connectors, 2 television plugs and a cable. In this case, a splitter for connection should be purchased with two outputs. If there are three of them, and one is unoccupied, then it will be necessary to connect a ballast resistor with a resistance of 75 Ohms to it.
Advice! If you plan to connect several more TVs in the future, you can immediately purchase a splitter for the required number of devices and plug the free outputs with ballast resistors.
The connection procedure consists of the following sequence of actions.
Features of connecting three or more TVs
When connecting three or more TVs to one antenna, you need to take into account that the signal in this case will reach the devices very weakly. This means that it will be possible to count to show only analogue channels, digital broadcasting is only possible with a very good source signal.
Advice! To get a good result when connecting three or more TV receivers to one antenna, you need to use only a high-quality cable with a resistance of 75 Ohms and frequency range up to 1000 MHz.
But in Lately All kinds of amplifiers are on sale, which (as manufacturers claim) are capable of multiplying the signal from one antenna to several TVs no loss in quality.
Connection diagrams two (a) and three (b) TV receivers to one antenna look like this:
Signal Boost
As mentioned above, the signal can be amplified using special devices. To improve initially weak signal, the user will need a special amplifier that is mounted near the antenna, and if the signal is good, but it is only enough for one TV, you should use an active antenna splitter. Read more about these devices and the features of their connection later in the material.
For active antenna with amplifier mains power required. In case of use outdoor antenna Finding an outlet nearby is problematic. In this situation, there are two ways to provide power to the device.
The first option allows you to supply voltage to the antenna directly from the TV through a cable transmitting the TV signal. This is possible through a special splitter that allows the passage of power supply, which can be identified by the Power Pass sign near one of the exits. A cable going to one of the TV receivers is connected to this connector, with the power supply at the other end connected to the socket.
Advice! Splitters with power supply are convenient when using DVB-T2 set-top boxes. In this case, power is supplied through the tuner, eliminating the need for another power supply.
The second method is relevant if such a splitter is not available (since it is a rather scarce product). In this case, you can provide power supply using a special adapter. On one side it has an antenna socket into which you need to insert a separator from the power supply. On the other side there is an internal thread and a needle, which must be screwed onto the input of the divider. After connecting the unit to the mains, power will flow even through a conventional divider.
It is better to take a power supply for the amplifier with voltage regulation in order to increase or decrease it if necessary. This may be relevant if the signal is amplified. In this case, when watching digital television video may freeze until voltage is reduced.
Splitter with amplifier
If the antenna signal is good, but it is not enough for several TVs, you can use a special active splitter. It looks like a regular splitter, but inside it is a chip and resistors. When connecting a couple of television panels, you can try to do without it, but if the signal is divided into three or more parts, it must be used.
Power is supplied to the active splitter in the same way as for an antenna with an amplifier. The cable going to the TV is connected to the output labeled “Power Pass”, with the power supply connected on the other side (first method).
Features of connecting to a satellite dish
You can connect a satellite dish to two TVs using several receivers or through a high-frequency modulator.
Via RF modulator
If the satellite dish is equipped with a high-frequency modulator, you can connect a regular splitter to its output, and from there run a cable to the television panels. In this case when you switch the channel on the receiver, it will simultaneously change on both TV receivers.
Advice! This inconvenience can be partially avoided by connecting one or both TVs to the receiver via RCA or SCARD. In this case, in addition to the satellite antenna, it will be possible to connect an outdoor or indoor antenna to the device, which will allow you to configure the display of regular over-the-air channels.
Through additional receivers
If you have not 1 receiver, but two, you can use them to configure the display satellite channels on different television panels. There are four ways to do this.
- The first way is serial connection . If one of the receivers has not only an antenna input, but also an output, you need to connect a converter to it, from which you can run a special one certified and suitable for satellite equipment cable to the second receiver. The disadvantages of this method are that to view encrypted channels you will need two cards, which requires double subscription fee. Also, with this connection, it is impossible to simultaneously watch channels with different polarization (horizontal and vertical) on two TVs.
- Second way - use of a special certified splitter(a standard divider is not suitable due to the difference in voltage required to power the converter and switch polarization). The head for the satellite dish (converter) is connected to it, and cables go from it to the TVs. The disadvantages of this connection are the same as in the previous method. Use this connection should only be done if none of the receivers have an antenna output.
- Another way - purchase and installation of a second converter. This will allow you to use two receivers independently of each other, but you will need to point them to different satellites, which means you will have to watch different channels. Each person will need their own card with a separate subscription fee.
- AND last method connections – using a receiver with two outputs for horizontal and vertical polarization. The cable from them needs to be connected to the multiswitch. And from this device you can connect up to three television panels. Then on all TV receivers you can independently watch channels in different polarizations, the multiswitch will independently make all the necessary conversions. However, cards must be purchased according to the number of receivers, and the subscription fee will also be paid according to the number of connected devices.
In conclusion, it should be noted that there are usually no difficulties in connecting several TVs to one antenna. This is a fairly easy process if you know the connection diagram and the correct sequence of actions. It is worth remembering that the antenna signal is divided into several parts, and if it is sufficient to receive analog channels, then digital television in the end it may not work.

Satellite TV can be connected to 2 TVs different ways— using a second tuner (receiver), using an RF module, etc.
One set of equipment for connecting to satellite television is designed to connect only one TV. Therefore, to connect two or more TVs, additional elements or another set of equipment are required.
Receivers for connecting two TVs
If one of the devices has not only an input, but also an output socket for an antenna (not to be confused with a modulator socket - it is designed to connect the device to a TV via high frequency), then you can connect a cable to this socket, which is designed to connect satellite antennas to receivers . Connect the second end of the cable to the input jack of the second receiver. You will get a serial connection of the converter and two receivers. If you receive encrypted channels, you will have to purchase a separate card for each receiver and pay a subscription fee. In addition, with such a connection, it will not be possible to watch channels with vertical polarization on one receiver, and with horizontal polarization on the other.
With this connection, the slave (second) receiver must be configured so that the “Power” option is disabled. Otherwise, problems may arise when viewing channels.
This connection option makes sense when the user wants to use one TV, for example, only for watching paid channels, and the other is for free ones.
You can use a splitter that is designed for satellite receivers and converters. This connection method will have the same disadvantages as the previous one. Additional equipment must be used if none of the receivers has an output jack for connecting a second device.
Installation of 2 converters on the antenna
If you install 2 converters (“heads”) on the antenna, you can connect them to two different receivers. They will work independently of each other.
But there is such a drawback: 2 converters cannot be directed to one satellite. You will have to watch different channel packages from different satellites. If the channels are encrypted, you will have to purchase 2 cards and pay 2 subscription fees.
Installing a converter with two outputs
Another option is a converter with two outputs. One of them can receive channels with vertical polarization, the other - with horizontal polarization. Both outputs need to be connected to a multiswitch, and parallel cables should be drawn from it to the TVs. On any of them you can watch channels that are broadcast in any polarization. All required switchings will be automatically made by the multiswitch. But for each receiver you will need a separate card and subscription fee.
If you want to use one receiver and one card, and the receiver has a modulator high frequency, then you need to connect the modulator output to two TVs through a splitter, which is designed for terrestrial antennas. Both TVs need to be tuned to the satellite TV channel that the modulator broadcasts. When you change the channel on the receiver, it will simultaneously change on both TVs.
You can connect one TV at a low frequency (for this you will need RCA or SCART connectors), and the second at a high frequency (for example, through a modulator). The result will be the same, but with this connection, you can connect a regular indoor or outdoor antenna to the first TV and independently receive over-the-air channels. And if one TV is connected via RCA, and the second – via SCART, then you can watch channels from a regular antenna on both TVs.
You can connect satellite TV to two TVs and through one receiver. In this case, the first device is connected to the first TV using a “tulip”, and the RF module is connected to the second output on the tuner, which is intended for connecting other monitors.
This method has many disadvantages. You can only change channels in the room where the receiver is located. And the main drawback is that both TV receivers show the same channel.
Divider installation
There is an option to use a splitter or splitter. These parts divide the signal from the antenna into 2.
This branching option has screw sockets. One end of the cable is stripped, inserted into the nut, the second with a similar plug is connected to the TV. There is a special hole in the splitter screw socket for the central antenna cable. You need to insert the end of the cable there, tighten the nut, and press the copper sheath tightly against the body of the device.
The procedure for connecting a satellite dish to two TVs is different for each model.
Instructions
Purchase a special cable of appropriate length, as well as a splitter with two outputs. The image quality will depend on the cable.
If one TV is already connected to the antenna, then the end of the cable must be removed from the TV and inserted into the output port on the separator, tightening the nut tightly.
Cut off a small end of the cable from the common skein, put standard plugs (heads) on the ends, and clamp them.
In the same way, connect the plugs to the large (remaining) piece of cable that will be used to connect the channel splitter and the second TV.
Plug all the plugs into the corresponding connectors on the body of the splinter and the TV.
Hide the cable that goes to the second TV under the baseboard or somewhere else so that it does not get underfoot. If possible, it is better to drill into the wall to run the cable to the second TV. This will make it possible to use a shorter cable length.
After connecting the antenna to two TVs, check the image quality on both receivers. If the quality is not very good, then check the fastening of all plugs at the ends of the cable and tighten them tighter.
Settings
- Press the menu button.
- Determine the desired source for the signal, select it.
- In the selected source, mark the connector to which the TV is connected.
- Start searching for programs.
- After completing the search, remove from the general list those channels that do not have a clear image.
The best option for connecting a satellite dish to several TVs
To watch different TV channels on 2 (3, 4, etc.) TVs, you need to connect a separate tuner to each of them. But such an elegant cable solution is very expensive.
You will need 3 separate cables, from the converter (“antenna head”) to each receiver - a separate cable. For this, there are special converters with different numbers of outputs - 2, 4, 6, 8. Accordingly, if you want to connect satellite TV to 3 TVs, you will need a converter with 4 outputs.
Splitter
It is considered the most financially profitable way to connect. The signal can be received from any satellite, but such a system will not always work acceptable.
Multiple output converter (LNB)
There are several modifications of this element, each with a different number of outputs - 2, 4, 8, 16. Each TV needs a receiver, or the TV must have a built-in DVB-S2 tuner and a CI+ slot for the CAM module. A separate cable is pulled from the converter to each TV.
There are convectors of the C and Ku ranges. All paid operators satellite television operate in the Ku-band. Ku-band satellite converter (LNB) is divided into:
- circular (“Tricolor-TB - Siberia”, “HTB-Plus-Vostok”) polarization;
- linear (“Continent-TV”, “Orient Express”) polarization.
This type of convector is considered the most reliable connection option with a minimum number of connections.
ST for several TVs
There is another option for connecting multiple TVs to multiple satellites. If it is necessary to connect a large number of subscribers to one antenna, then a special device is used for this - a multiswitch, which divides the signal into several convectors. Most often, this element is used to create a network with a large number of users (for example, in urban apartment buildings). If you need to connect CT to several TVs in a private cottage, then it is more convenient to use convectors with independent outputs.
CT from several satellites to several TVs
For this connection option, in addition to convectors with independent outputs, devices such as “diseks” (“daiseki”) are also required. They are designed to receive signals from different satellites via one cable. Dishes are adapted for different protocols. The protocol standard for which a particular drive is intended is indicated on the packaging or on the device itself. For example, “DiSEqC 1.0 – up to 4 convectors.” For the entire system to work, the receiver must also support the standard for which the disc is selected.
Special offer from Tricolor-TV - set for 2 TVs
This operator makes a unique offer to customers - a special set of equipment for two TVs. This is considered the optimal connection option, because it is possible to satisfy the interests of all residents of one apartment without significant financial costs.
The most complete kit, which will allow you to connect everything without unnecessary hassle, includes:
- an antenna (“dish”) equipped with a converter with two outputs;
- receiver GS E501, which combines the functions of two tuners (or another receiver model with similar capabilities);
- attachment GS C-591;
- 2 remote controls and 2 power supplies;
- access card;
- cables for connecting equipment to the antenna;
- “twisted pair” for connecting the set-top box to the receiver;
- HDMI cables for connecting TVs to set-top boxes;
- documents and instructions.
If you have a receiver with two tuners installed, you can purchase a client set-top box. It costs less than a regular receiver, but you will need to pay separately for the viewing service on two TVs. In addition, the operator offers to exchange, with an additional payment, the existing equipment for a new one.
There is no need to install a double converter on the antenna instead of a single head with one output. It will be enough to install an antenna divider near the receiver, where the coaxial cable fits.
Easy connection
A smart card is inserted into the main receiver (CS E501); there is only one in the sales kit. Two coaxial cable, coming from the two outputs of the converter on the antenna, are inserted into the LNB IN inputs No. 1 and 2 on the same device.
The device plays the role of a server that is capable of decrypting the signal and transmitting it to the GS C-591 client set-top box using a twisted pair cable. After this, all that remains is to connect TVs with set-top boxes using HDMI cables, and you can start searching for channels.
You can configure both devices to adequately display the signal using the appropriate instructions, or use the tips in the video. If everything is done correctly and the operator’s services are paid, then both TVs will show channels independently of each other.
Advantages of this connection option:
- Firstly, there is no need to install a second antenna.
- Secondly, you don’t need to buy a second receiver if you buy a client set-top box, which costs less.
- Thirdly, connecting to one TV costs 1,500 rubles, and to two – 2,000. A system for two TVs costs 1 thousand rubles less.
As a rule, one digital set-top box is designed to connect one TV. If there are several TVs and all of them do not support the DVB-T2 standard, a separate receiver should be connected to each TV. Despite the low cost of set-top boxes, many people want to minimize costs and use one set-top box for at least two TVs. This is possible, but with certain limitations:
- One of the TVs must have a digital HDMI input (old CRT TVs cannot have it).
- Both TVs will show the same image; viewing different digital channels in this case is impossible.
- Channels are switched on the remote control of the set-top box, and the remote control only works in the line of sight of the set-top box. That is, if you watch TV in one room and the set-top box is in another, you will need to go to the other room every time you change the channel.
A typical example of the use of such a scheme is when one person watches channels from digital set-top box alternately in different rooms, for example, in the room and in the kitchen, and does not need to constantly switch channels. However, with a good location of the rooms and good reflective surfaces, the signal from the remote control can “fly” to another room through an open door.
Connection diagram for DVB-T2 set-top box for two TVs
If the limitations listed above do not scare you, then you can connect the digital receiver according to the diagram shown in the figure. The first TV, with an HDMI input, is connected with an HDMI cable to the corresponding output of the set-top box. The second TV is connected to the set-top box using an RCA cable, which is usually called “tulips”.
If the distance is small, then you can use a ready-made RCA cable the required length (usually they are no more than 5 meters). If it is not possible to buy a ready-made cable, you can purchase RCA plugs and use a regular cable to transmit the signal. To transmit an image with stereo sound you will need three cables, for mono sound two will be enough. We recommend using the plugs shown in the illustration. They are reliable, easy to use and do not require any tool other than a knife for installation. Initially, an F-connector is installed on the cable, and then an RCA plug is screwed into it.
The cable splitter cannot be used if satellite operator uses different polarization for different channels (for example, Tricolor). In this case, connect a converter with two outputs.
How to choose a cable splitter
When choosing a cable splitter, consider the following parameters:
- Bandwidth
Different types of television signal (terrestrial, cable, satellite) have different frequency Accordingly, the splitter must have an appropriate frequency bandwidth. For example, for terrestrial television support for frequencies of 5 - 1000 mHz is sufficient, and for satellite, a band of 5 - 2400 mHz is needed. That is, a divider for satellite TV can be used for terrestrial TV, but not vice versa. - Number of outputs
It is easy to understand that you need as many outputs as there are TVs you plan to connect. There are television splitters with 2, 3, 4, 6 or 8 outputs. In order not to “wastely” weaken the signal, it is recommended to purchase a divider with the number of outputs needed right now. These devices are not that expensive, and when you buy another TV, you can replace the splitter with another one with the required number of outputs. If you still buy a device “for growth,” install a resistor on unused outputs that will absorb excess voltage in the circuit (up to 75 Ohms). - Cable connection method
— screw clamp: suitable for cables of any diameter and does not require soldering
- thread: only for thin cable, does not require soldering
— coaxial sockets: cable diameter is not important, connection via plugs
— splitters that require soldering: the most reliable connection, but special skills are required - Signal attenuation rate
Information about this can be found on the case or in the instructions for the television splitter. The lower the signal attenuation, the better. - Manufacturer
Recommended manufacturers of cable splitters: Lans, Rexant, Premier, Alda, Hama, Sat
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 go with 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.
Work order
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's another one here important point, which 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, they are always more reliable, they imply 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 optimal option is considered to be approximately equal distance from the splitter to both TVs. 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.
Antenna with amplifier
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.
