The working principle of the application circuit of the device is shown in Figure 3. Usually, the power switch of the shared antenna amplifier and the user's TV are separated. Sometimes no TV is working, but the antenna amplifier is still powered on, wasting energy in vain. At other times, there may be multiple TVs receiving programs, but the power switch of the shared antenna amplifier is not turned on, which of course does not get a good reception effect. The use of LCE module can be easily controlled automatically.

When any of the TV sockets CZ1, CZ2, CZ3 (of course, more power sockets can be designed and installed as long as the LCE power used allows) is plugged in and the TV power switch is turned on, the power of the shared antenna amplifier will automatically supply power. This will not waste power, will not affect TV users, and does not require special management.
