Very often a second television appears in the same 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 for two or more televisions.

What is required
A few parts are required for the connection:
- two-output splitter (splitter). This device allows you to split 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 TV receivers.
- 5 connectors corresponding to the splitter;
- 2 adapter plugs;
- antenna cable.
Important: When purchasing a splitter, do not confuse the number of outputs! A three-way (three-output) splitter is used to connect three receivers, but not two! If you still have three outputs at your fingertips, you can solve the problem by connecting to the free output of a ballast resistor (75 Ohm resistance). And if there is a plan in the future to install and connect several TVs to this antenna, then it is better immediately buy a splitter with several outputs and temporarily drown out the empty outputs with the same resistance.
We will try to talk about the connection in such a way that even someone who does not understand radio engineering at all could cope with the task. This is done step by step:
- Choose the details. The first thing you need to buy a splitter. They are different, including those that need soldering, and those that do not need it. If you know how to solder, it is better to take those that involve soldering. This connection is always more reliable than any other, it gives less signal loss, preserves its quality.
If you do not have soldering skills, then you need to choose a splitter appropriate, as well as suitable for a particular type of cable. A win-win option would be a splitter with integrated jacks for coaxial cables.
After selecting a splitter, select the appropriate connectors. Now F-connectors are very popular due to the fact that they are reliable, easy to install.
- Choosing a place for the splitter. It is optimal to position the device so that the antenna cable freely reaches it and, if possible, there is the shortest distance to both TVs.
- Trim existing antenna cable. It is necessary to cut so that the cable freely reaches the splitter. An old plug is cut off along with a piece of cable.
- Cable Cutting and Installation F–Connector.
For those who can solder, it makes no sense to tell how to cut the cable and solder it to the splitter - they themselves know this. The following is written for the average user who is not familiar with the radio case.
So, we cut the trimmed end of the wire, as shown in the figure: we clean the edge, wrap the braid. The insulator of the middle core should protrude slightly, and the middle core should protrude at least 5 mm. An ordinary kitchen knife serves as a tool for removing insulation from a coaxial cable at home.
Important: The cable should be standard, most commonly used are DG 113 or SAT 703B. The cable sheath should in no case be connected to the central core, otherwise the signal will not pass at all.
Install the F-connector. It is also called wrapping, because the connector is wound on a soft wire. The connector for connecting the cable and splitter is ready.
- Cut off two pieces of wire with the expectation that the length is enough for each TV.
- Mount Fconnectors similarly for connecting television cables and splitter outputs. At the other ends of the cables we do the same.
As a result, we have all five connectors involved, including:
- one from the antenna to enter the splitter;
- two television, for exits from it;
- two television 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 to one end, and a coaxial plug for connecting to TV sets on the other. Usually this device is called a whole plug.
- Turn on the television. We check how both receivers work. If everything is done correctly, then the image should be normal. Now you can easily enjoy an excellent picture at once on two receivers, without interfering with each other.

How to install an antenna with an amplifier
But what if, after connecting the splitter, the image quality deteriorated? This may mean that the antenna on two televisions does not provide the desired signal, while the separation device also takes on some of its share. An output can be an antenna with an amplifier, it is also called Polish. Such an antenna for two television receivers connected to the device will improve the signal quality in both televisions. To do this:
- In an existing splitter circuit remove F-Socket from the entrance to it.
- In its place put plug with power supply from an antenna kit with an amplifier.
- At the entrance install an adapter with an antenna socket (the so-called “mother”) and insert the plug from the antenna with the amplifier there.
This should improve signal quality.
There is a second option - look for a splitter with a built-in signal amplifier. This method is good when initially the TV showed good and a new antenna is not required. However, before purchasing a new device, discuss your specific case with a specialist.
Amplifiers, including those on the antenna, have different amplification factors, and too large a signal is just as bad as a weak one, and it can also cause distortion. The telemaster will measure the signal level and give advice on acquiring an amplifier.
By the way, the problem with signal attenuation can be even more difficult if several TVs are connected to the same antenna. The more receivers, the stronger the signal attenuation. Therefore, planning to connect several television sets, weigh all the arguments “For” and “Against”.
