Antenna Switch


  • Antenna Switch with 12inputs by two output remotely controlled.
  • Aluminum cabinet painted in the dark gray color, having UHF type (SO-239) for the R.F connections and DB-25 for remote control.
  • All antenna inputs are switched to ground when not in use.
  • When the power are switched off, all antenna inputs are routed to ground for protection purposes.

12 antennas 2 radios solution diagram
The switch AS-1202F receives the signals from twelve antennas selecting one of them for each radio (two of then), leaving the others not in use, shorted to ground. In the case of power supply disconnection, the radios became free and all antennas are grounded.
