Frequency · 118-137 MHz 

Designed specifically for mounting to the underside of an aircraft providing excellent radiation coverage for air-to-ground communications.

Bent configuration makes it ideally suited for helicopters and low wing aircraft.

The CI-122 has been re-tested and upgraded to the new RTCA DO-160D environmental requirements and offers the 118 to 137 MHz frequency associated with DO-186A MOPS.
