Antenna splitter for 2 TVs - which is better to choose?

So answer - without which the New Year is impossible? More than sure that you will remember the Christmas tree and the TV. Together with Olivier salad, tangerines, it has become an invariable attribute of the holiday, which sets the mood, creates a festive atmosphere. The times when the whole family gathered in front of one TV have disappeared. Now he stands in every room, kitchen, and, as a comedian noted, even a cat has a small TV. To make sure that each member of the family watches an interesting program for him, an antenna splitter will allow.

Antenna splitter

An antenna splitter is a passive device that will divide the signal between all connected devices so that everyone watches the broadcast with the same quality. Losses (interference) will be minimal. Depending on the needs of the user, there are three varieties:

Splitter (divider). This is a splitter that divides the input signal evenly between connected devices. Optimal for connecting up to 3 devices. If more - you will need a splitter with an amplifier.

Diplexer (adder). It mixes signals of different ranges, for example, satellite and terrestrial channels, and then transmits via a single cable. At the entrance of the apartment, it works on the opposite principle - they share the received signals, connect the signal from the satellite or broadcast to the users' TVs. The design includes filters that minimize interference.

Tap (tap). Distributes the signal over the main intra-home network. For example, the network of an apartment building. The number of outputs is equal to the number of connected devices. Due to its wide range and normalized attenuation coefficient, it levels the signal level throughout the network.

Most often they put a splitter on the cable entering the apartment, which distributes the signal across the rooms. Therefore, recommendations will be on which one to choose.

Instrument design

The design is a small box of light metal - brass or silumin, with F-connectors and ears for mounting. On the one hand, a plug for the incoming cable, on the other hand, from two or more - for connecting devices. The case is hermetically sealed. A paper with the name and characteristics is glued on the top cover.

IMPORTANT: The device will be better if there is an RF transformer with high resistance in the composition. Minus - they are expensive and can only divide the signal into two TVs. If this is not enough, then buy a divider with several resistors connected in series.

Choose a splitter

First, the parameters to consider when choosing:

Define a range of frequencies, channels.
How many devices are planned to be combined.
Determine the cross section of the cable.
Set the qualifications and desire of the performer.

The choice according to the following algorithm:

We go to the TV menu, we find a table with the frequencies of all channels received by the receiver. The high frequency should be in the range of frequencies at which the splitter operates.
We consider the devices that you plan to connect, add a few for the future. Choose a splitter with the required number of outputs.

We look at the attenuation of the signal. It is designated in dB. This parameter is written on the device case or passport. The lower the value, the better.

Appearance. Since the device will be in sight, then take care of the appearance. If you plan to place inside the cable duct, the divider should fit freely there.
Fasteners. On the case, usually provided for mounting holes. It should not just hang out, because it is not beautiful, it is possible to bend or rub the contact of the wire, which means failure.
Choose the connection method based on: which cables are used, from your own skills and abilities to connect two wires, to carry out high-quality soldering. On sale there are splitters with screw connection, but they are designed for thin cable. If you are not confident in your abilities, then take one. Devices with coaxial connectors are sold. You can use any diameter of the cable here, but first you have to solder the antenna plug.

Make no mistake when buying - choose a splitter, and not a similar device, a device for another purpose. Consult the seller, look on the Internet how it looks.

The connection includes several simple steps and takes no more than 20 minutes:

We find a flat surface near the entrance to the apartment. We install in such a way that it is convenient to let the wires departing from it. If necessary, close it.
Remove the plugs from the connectors.
We insert the cables into the socket of the antenna of the TVs, fasten the second end to the connector of the divider.
We connect the input antenna cable to the splitter input.
