Feasible method:
The satellite antenna interface is preset on the balcony, and then the signal is distributed to each room through the satellite signal distributor. If you need to watch satellite TV, you need a satellite TV receiver in this room.
(Note: The best satellite TV signal line, directly connected to the receiver, do not use the wiring panel to prevent signal attenuation)
More advanced (complex) methods:
Purpose: The satellite signal can be mixed into the cable TV signal in the room. In this way, it is possible to do wired wiring only in the house and watch satellite TV through the cable.
Disadvantages: It is still necessary to go to the satellite receiver to select channels, so I think it is not particularly practical for the average resident. . . .
method:
1. Satellite receivers have radio frequency (RF) output. Now many models of Cost-down have simplified the elimination of RF output.
2. The RF output is modulated in the UHF section and adjustable to avoid interference with cable TV.
3. Receive the satellite radio frequency to the cable TV and use a high-quality two-distributor as a mixer to mix the satellite TV with the cable TV. (High quality -> open the lid, the inside is directly connected with the wire is a fake, at least capacitors, inductors, good use of PCB)
4. The second distributor is a passive device that transmits in one direction and does not interfere with neighbors. JS purchase price of about 3 to 5 yuan.
5. Some radio frequency modulators have poor quality and can interfere with cable television on other channels.
6. After fine-tuning the output channel, the video and audio are clear, and other channels do not interfere.
Another advanced method:
Now that there are 2.4GHz wireless audio and video transmitters that can transmit across the wall, there is no need for wiring.
(But it's best to have a wall remote that can control the channel.) D)
My thoughts: Just buy one more receiver and save more. . . . . .
