How to design distribution wiring for hotel cable TV (analog)?

There should be multiple connection methods. The simplest one should be to connect the main output port of the amplifier to the 2nd floor, and connect the branch port to 6 and distribute it to the 3rd floor. Pick up a 204 or 106 on the 2nd floor, take the main road to the first floor, and pick up a 6 on the 2nd and 3rd floors respectively. In addition, each TV can be connected in series, using a branch, going down the main road, and entering the TV from the branch. The models are 114, 112, 110, 108, and 106. The key is to ensure that the level entering the TV cannot be lower than 60dB, but not higher than 80, the national standard is 68-72. In this way, the amplifier output is 85-90.
