The AV-927 diplexer can be used with airborne multiband FM transceivers. The device is designed to provide two separate frequency band ports (typically going to a multiband transceiver) from a single port multiband antenna.

The AV-1 is a base station antenna for VHF communications with ground vehicles or aircraft. It has heavy-duty construction with 3/8″ diameter aluminum radials and a 1″ diameter aluminum tube radiator. These elements are treated with a “hexavalent free” passivation process per MIL-81706 and MIL-5541 for superior durability. It mounts easily to a 1″ diameter pipe or a 1-1/4″ O.D. tube with locking set screws. A built-in gap-type lighting arrestor is an important design feature. The antenna operates at a frequency of 118 – 137 MHz, and requires no additional tuning. It is designed to withstand wind speeds of up 100 mph.

The AV-587 antenna coupler is an antenna signal splitter/diplexer providing three outputs from a single antenna. One output provides a combined VOR/LOC/GS signal. A second output provides a combined VOR/LOC signal. And a third output provides a GS signal.

The AV-586 antenna coupler is a signal splitter providing two outputs from a single antenna. The necessity of bringing this product forward comes from advancing technology in avionics. Newer designed navigational radios have only one antenna input to receive all three (VOR/LOC/GS) signals whereas older legacy radios had a separate antenna input for the VOR/LOC signal and another antenna input for the GS signal. In an aircraft instrument panel with two newer navigational radios the AV-586 is the article that will provide the necessary signals to both radios utilizing a single antenna.
