RAMI AV-590 & AV-590(-28) COM Electronic Switch
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.
RAMI AV-1 Base Station | VHF
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.

VHF Communications Antenna | 118-137 MHz, 4 Hole Mount, BNC Female Connector, Gloss Black
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.
CI 292-1 VHF Whip Antenna | 118-137 MHz, BNC
The CI 292-1 is specifically designed to be mount on top of the aircraft while providing excellent omni-directional coverage for all VHF communication frequencies. The CI 292-1 features a straight, tapered stainless steel radiator. This antenna has been updated to meet RTCA DO-160D environmental requirements while offering frequencies from 118 MHz to 137 MHz associated with DO 186 MOPS.
RAMI AV-300 ELT Communication
The AV-300 ELT antenna is intended for use with a 406 MHz ELT (Emergency Locator Transmitter) for General Aviation. It is a passive three frequency fiberglass rod whip antenna, designed for low speed aircraft (up to 350 knots). It has met DO-160G, Section 8, Category U requirements for robust vibration and is qualified for installation on helicopters with unknown rotor frequencies.
CI 273 RADIOPHONE STUB ANTENNA/BNC Connector, 403-512 MHz, 50 Ohms, 50 Watts, Airspeed 250 Knots
The CI 273 is a UHF radiotelephone stub antenna has its electrical performance specified over the frequency range of 403 MHz to 512 MHz in various band segments. It is also designed to withstand the environment associated with the underside of an aircraft. The antenna radiator is mechanically captivated and seated against leakage. All exposed metal surfaces are nickel-plated for corrosion resistance and long service.
