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.

| 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.
