Introduction to the installation method of cable TV distributor

[ Huaqiang Security Network News ]

Cable TV splitter installation is part of the entire cable TV installation. Proper and careful installation ensures that the TV signal is not lost and provides a good experience for the user. Therefore, Xiaobian introduces the installation method of cable TV distributor by introducing the installation of cable TV.

TV distributor

1. Since the distributor will generate signal attenuation when performing signal distribution, it is necessary to install a free amplifier when installing cable TV in the building. A cable TV amplifier has only one output port, and the other ports are detection ports. If you want to pick up 5-6 TV sets, there is no problem. The amplifier usually has 40 terminals and there is no problem.

2, cable TV distributor and amplifier connection

(1) First adjust the output battery of the amplifier to 103-105dB. According to the distance of the TV, that is, the data line you said, that is, the 75-5 cable, calculate the distance from each TV to the amplifier, 75- The 5 wires lose 20 batteries per 100 meters. Then connect the splitter to the amplifier output with a wire at the output of the amplifier. Then add the distributor according to the distance from the amplifier to the terminal, and lay 75-5 cable from the output port of the distributor to each terminal (that is, each TV), and ensure that the battery signal from the distributor to each terminal is 65-75dB. Between so, each motor can normally receive TV programs.

(2) The models of the distributor are: 407, 306, 204. The splitter distributes the signal evenly to each output port (for example, the 306 distributor, which inputs a 100dB signal, and the output of each of the three output ports is 94dB)

3. The state stipulates between 60 and 80 dBuv. If the signal can reach more than 75, you don't need an amplifier. You can buy a multi-port splitter. If the signal is not enough, you should use the amplifier. First of all, you need to know how much your amplifier is amplified, too much amplification is not good, it will affect the effect of the input signal to the amplifier input end with an output port serially connected to a multi-port allocation, the saved output port is used for spare.

When installing the cable TV distributor, pay attention to the core wire inside the cable, that is, the copper wire and the outer shielding net can not be connected, and the short circuit will be shorted together, which will affect the signal.
