COM electronic switch - AV-590

AV-590 & AV-590(-28)

COM Electronic Switch

The AV-590 is an electronic switch allowing two COM radios to share the same COM antenna.

In receive mode, it acts as a signal splitter allowing both COM radios reception across the entire COM band (118-137 MHz).

In transmit mode, which ever COM radio (COM 1 or 2) is selected through the audio panel, a control signal is sent to the AV-590, switching the selected COM radio to the COM antenna and isolating the remaining COM radio from the COM antenna.

Once no longer transmitting, the control signal is removed and the AV-590 electronic switch reverts back to the receive mode as described above.
