Simplify the insallation of a station preamplifier with the LNA Technology RFCA series RF switched preamp.
A high performance relay package and
RF detector switching circuit detects the presence of transmit signal, and quickly switches the transmit power around the preamp.

Power source and feedline installation are all that is required to add receive system gain.
Modular RF isolation construction, allows use of any CA / CF / SA / SSA series preamp.
RF rated coaxial relays, not “open frame type”
160 / 250 Watts 50- 399 Mhz
Switches preamp out of line when transmit RF is detected.
Preamp and relays all in one mast mountable package.
External switching command line with RF over-ride allows hard switcning of relays via sequencer or other control systems, with
RF detection back up, in the event of a
control system failure.
