The VHF Communication Antenna Mount Kits provide either one or two flat mounting locations for installation of Comant VHF Communication Antennas on the bottom of the tailboom. Comant CI-121, CI-122, CI-177 or CI-177-1 Antennas may be installed in either or both locations depending upon system requirements. By installing the antennas on the tailboom it allows for additional optional equipment or larger mission equipment to be installed on the belly of the aircraft. The VHF Communication Antenna Mount Kits are engineered for ease of installation and each kit includes detailed instructions, drawings and hardware.
