How Many Televisions Can Connect To One Antenna
Connect T2 signal to multiple TVs
recently, the final verdict from the state was heard about the phased disconnection of analog television and the transition to digital terrestrial television T2 starting from June 2018.
For some, this news was not a surprise or a thunderbolt, because have already managed to update television equipment, starting from modern TV with built-in T2, ending with the acquisition digital terrestrial receivers. But there are also such households for which this is not the most pleasant news, because they could receive an analogue signal still existing in the broadcast.
In addition, we live in a time when television is not a luxury, but a popular and accessible to many means of obtaining information of various plan and subjects: from news to entertainment. And the presence of two or more televisions is the most common phenomenon that you won’t surprise anyone with, and someone just plans to purchase an additional TV. That’s exactly for you the information will be interesting, How to connect a T2 signal to multiple TVs.
There are several ways to solve this problem. And the first thing we will determine: the number of TV sets in the house does not have the same number of decimeter antennas. a myth that many of our customers believe in.
To receive a T2 signal, having more than one TV available is enough:
- just one correctly selected terrestrial decimeter antenna. type “wave channel”. Such antennas have the highest signal gain in the range 450-850MHz.
The larger the size of the antenna itself and the number of elements in the structure, the greater the self-amplification coefficient, and then there will be no need to use a signal amplifier, which is located in the mounting box on the antenna itself.
Using the antenna in passive mode without an antenna amplifier. guarantee of the longevity of her work.
Log-periodic and all-wave antennas (gratings, etc.) are designed structurally for the meter and decimeter frequency ranges, therefore they will be less effective in receiving the operating frequencies of the T2 signal.
In the coverage area (2-3 km) from the repeater, you can use any antenna, even indoor, and receive reliable reception of all broadcast channels.
At a greater distance, it is better to use an external directional decimeter antenna. If necessary, it is possible to use an antenna with an upper antenna amplifier.
- subscriber amplifier. a device for compensating for signal loss in the cable, distribution elements, connections and sockets.
The task of the home amplifier is to deliver a signal to each receiving point with the same quality. But you need to remember that if the signal at the input to the amplifier is weak, then the amplifier will not solve the problem of signal equalization.
Do not forget that when connecting two or more televisions or digital receivers to the same antenna, the received signal must be stable and reliable.
One digital terrestrial receiver is designed to connect to one TV, i.e. if you have three televisions, then ideally there should be three consoles or you need a new generation TV with an already built-in T2. This implies the second myth, or rather the hope of consumers to reduce and minimize equipment costs. this is the desire to use one set-top box on several TVs. In principle, this is possible and feasible. For this you need receiver with rf modulator. Such devices can be used for any number of TVs. But you must remember the features of this use and connection. the picture on all TVs will be the same.
Thus, the optimal set for connecting a T2 signal to several TVs is as follows:
