The AV-590 allows two communications radios to share the same antenna.  In the nominal, non-switched mode the AV-590 splits the signal from the antenna evenly between two comm radio receivers.   When the control voltage is activated by the microphone PTT, the AV-590 switches the antenna to the corresponding radio transmitter and isolates the other receiver.
