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 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.

This CI-505 Diplexer (CI-505-TNC) has TNC connectors.

The CI 505 Dual VOR coupler/single GS diplexer allows the operation of two VOR receivers and one glide slope receiver from one VOR/GS antenna. The compact design provides for easy installation.

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 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-17 is designed specifically for mounting to the underside of an aircraft, providing an excellent radiation pattern for air-to-ground communications. It has a 4-bolt mounting base and is low in profile. 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 0.66 lb @ 250 mph. This antenna is a direct replacement for the CI 122. This VHF communications antenna has a gloss black finish.
