If length of cable from antenna or amplifier to the TV is large (more than 20 m), better to use the Antenna Switch of High-frequency Signals (pic. 1).
Pic. 1. Antenna Switch of High-frequency
Signals Circuit.
You can use high-frequency impulsive diodes КД512 and КД514, taking into account the legitimate middle values of direct current and legitimate values of reverse voltage.
