Connect a short 50-ohm cable with PL-259 connectors between the transceiver antenna
connector or the receiver antenna connector and the RADIO connector on the transmit/receive
switch.
Using a 50-ohm coaxial cable with BNC connectors or other connectors and BNC adapters,
connect the transmit/receive switch RECEIVE ANTENNA input to the loop amplifier output.
Connect the 12 VDC power adapter and turn the transmit/receive switch power switch to ON.
After a short delay, the RECEIVE LED will illuminate.
Turning the antenna switch power off or removing its power source will disable the receive loop
antenna.
In this receive-only configuration, the red LED is a power indicator. Transmit/Receive Switch
PTT and Transmit Antenna connections are not used.
NEVER CONNECT THE TRANSMIT/RECEIVE SWITCH RECEIVE ANTENNA CONNECTOR (BNC) TO THE
TRANSCEIVER ANTENNA CONNECTOR OR THE TRANSCEIVER RECEIVE ANTENNA CONNECTOR. THE
CABLE FROM THE TRANSMIT/RECEIVE SWITCH TO THE LOOP IS USED FOR BOTH THE RECEIVED RF
SIGNAL FROM THE LOOP AMPLFIER AND 12 VOLTS DC POWER FOR THE LOOP AMPLIFIER. THAT 12
VOLTS DC COULD DAMAGE THE INPUT TO A TRANSCEIVER OR RECEIVER.
NEVER CONNECT THE OUTPUT OF A TRANSCEIVER OR POWER AMPLIFIER TO THE MAGNETIC LOOP
AMPLIFIER. THIS ANTENNA IS FOR RECEIVE ONLY.
