The AV-924HS antenna was developed to be used with airborne FM transceivers typically used in first responder type aircraft providing a single antenna solution for the multiband transceivers. This antenna operates at VHF and UHF frequencies. It meets DO-160G, section 8, Category U requirements for robust vibration and is qualified for installation on helicopters with unknown related rotor frequencies. The AV-924HS meets the environmental requirements for flight speeds up to Mach 1 and supersedes the AV-924 part number. It is the same form, fit and function.

The AV-925 antenna was developed to be used with airborne FM transceivers. It is typically used in first responder type aircraft providing a single antenna solution for multiband transceivers. It has met DO-160G, Section 8, Category U requirements for robust vibration and is qualified for installation on helicopters with unknown related rotor frequencies. It is also qualified to perform as a 406 MHz ELT antenna, and is well suited for this function on higher speed, fixed wing aircraft.

The AV-928 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-929 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-930 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 AVT-4 is a broad-band VHF communications antenna. It incorporates a low drag blade housing design for high strength and a radiating element encapsulated in rigid polyurethane foam. The housing is finished with a Skydrol resistant white polyurethane paint and comes with mounting hardware and neoprene mounting pad. The antenna is designed to operate at speeds up to 350 mph and altitudes of 50,000 ft. It has a drag force of 0.85 lb. @ 250 mph.
