The RAV30512 is a broadband, airborne communications antenna that is designed for airspeeds less than Mach 1. The antenna housing is constructed from a fiberglass epoxy that is designed to withstand exposure to sand and dust particles in desert areas. Extreme temperature changes, humidity, shock and vibration are reduced due to its foam filled core.

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 AT-1108ARC Antenna is a combined VHF/UHF airborne communications blade antenna designed for usage airspeeds of less than Mach 1. The antenna housing is fiberglass epoxy, designed to withstand the exposure to sand and dust particles of desert areas and is foam-filled to reduce the effect of extreme temperature changes, extreme humidity, and excessive shock and vibration. The AT-1108ARC is produced to Military Specification MIL-A-55680 and has continuous operation altitudes of up to 50,000 ft and temperatures between -65°F and 131°F. It can withstand the impact shock of 30g and the steady-state acceleration of 6g. The isolation between the bands is > 40 dB. A gasket for RF shielding and positive sealing is included. The antenna is coated with a Skydrol resistant lusterless CARC black paint.

The AT-640A/ARN Antenna is a receive-only VHF Marker Beacon antenna used on both fixed-wing and rotary-wing aircraft. The antenna meets the requirements of Military Specification MIL-A-5999 for electrical and environmental performance. Finished with a white Skydrol resistant polyurethane paint in accordance with Military Specification MIL-C-81773.

The AT-256A/ARC Antenna is used for airborne communications on various fixed-wing and rotary-wing aircraft. The antenna is produced to Military Specifications MIL-A-5815 and MIL-A-5815/1. The antenna is designed to operate at the extreme temperature range of -65°F to 257°F with intermittent operation at 302°F and can withstand a static load of 8 psi perpendicular to the blade, with an ultimate of 12 psi. The antenna is protected by an anodic coating to prevent corrosion and the outside surfaces will resist particular erosion up to Mach 0.95.

The AT-741B/B antenna is designed for use with Radar Interrogation. Constructed from an aluminum casting provides protection from particle erosion of speeds of up to Mach 2. This antenna is produced to Military Specifications MIL-DTL-25708 and is qualified environmentally to Military Standard MIL-STD-810. The AT-741/B/B can withstand a static load of 15 psi perpendicular to the blade, operate at altitudes of 100,000 ft, and has a Skydrol resistant lusterless CARC black coating.

The AV-931 Diplexer can be used with airborne multi-band FM transceivers. The device is designed to provide two separate frequency band ports (typically going to a multi-band transceiver) from a single port multi band 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 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 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.

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.

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-525 is a VOR/LOC/GS antenna similar in style to the AV-12 but utilizes an internal balun transformer. The antenna is rated at speeds up to 350 mph and altitudes up to 50,000 feet. It is a direct replacement for the CI 157P.
