Functional Operation

The antenna relay module contains a relay with a set of normally open and normally closed contacts. A
signal from the transceiver module controls the relay coil connected to the Receiver input port RX-A or
the PA deck to a single transmit/receive antenna.
NOTICE: With the relay de-energized, the antenna is connected to the Receiver input port RX-
A. To connect the antenna to the PA deck, the transceiver module must energize the relay.
