Overview
Frequencies Covered
118-137 MHz
Designed specifically for mounting to the underside of an aircraft providing excellent radiation coverage for air-to-ground VHF 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 118 to 137 MHz frequency associated with the DO-186A MOPS.
Note: Comant Antennas no longer come with a gasket or template. Must order PN 09-05579 separately.
