The dream is all there is to achieve. Today boiled here to tell everyone to crack the wide motor top box tutorial.
Want to see the big hair, see the reply:
1. Put the set-top box near the high-frequency head of one of the TVs (TV 1) so that it can be viewed normally, and then use the splitter to branch off the signal from the output to the other TV. One disadvantage of this approach is that the other TV set can only receive 5 channels near the channel that TV 1 receives.
2. Use an off-or gate circuit or 555 circuit to create an open multi-vibrator, whose resonant frequency can cover the entire frequency band of cable TV. (Production costs about 6 yuan) Place this vibrator next to the set-top box. Let the set-top box receive the signal from the vibrator, and then use the splitter to branch out from the output of the set-top box to multiple TV sets. In this way, all TV sets can receive signals from all channels.
3. Use a high-frequency transistor such as the 9018 as a high-frequency transmit circuit, and use the RF output to transmit again. As long as the small transmit power, the set-top box can receive it. Or use the coaxial video line branch access input or output, remove the outer shield, leaving only the middle of the line length of about 1 meter, this line around the set-top box. Let the leaked signal sense the set-top box to receive.
