Gasket for DM N4-15 antenna

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 CI 291 features a high strength fiberglass “stick” radiator and die-cast three-hole mount aluminum base. This antenna has been re-tested and updated to meet RTCA DO-160D environmental requirements while offering 118 MHz to 137 MHz frequencies associated with DO 186 MOPS.

The CI 122 has a stainless steel bent whip antenna element and diecast aluminum base. Designed specifically for mounting to the underside of an aircraft, providing radiation coverage for air-to-ground VHF communications.

The AV-520 is a “V” style VOR/LOC/GS antenna utilizing detachable painted stainless steel elements and 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 159C.

The AV-532L is a VOR/LOC/GS receive only antenna. It consists of taper ground high-strength 17-7PH stainless steel elements to reliably withstand vibration and wind loads. The insulators are weather-sealed compression-molded bakelite with the mounting holes provided. The unit may be mounted with the V pointed either forward or aft. The antenna is designed to operate at speeds up to 350 mph and altitudes up to 50,000 ft. It has a drag force of 3.42 lb @ 250 mph. A 30 foot transmission line with integral balun is also supplied.
