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-5 is an economical Ground Plane base station antenna for general aviation. It is ideally suited for use with Unicom transceivers and is field tunable to optimize VSWR at desired frequency. Durably constructed of high quality materials for a long operational life, the antenna is designed to withstand wind speeds up to 100 mph.

The AV-534 is a heavy-duty stainless steel quarterwave VHF communications antenna. It is manufactured with a durable type stainless steel whip and large stress-relieved ferrule and comes complete with porcelain insulators and mounting hardware. The antenna is designed to operate at speeds of up to 350 mph and altitudes of 50,000 ft. It has a drag force of 0.56 lb @ 250 mph.
