Frequencies Covered
118-137 MHz
Features high strength fiberglass “stick” radiator and die-cast 3-hole mount aluminum base. Virtually identical in appearance to many Cessna communication antennas and most LORAN antennas.
The CI 291 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.
Note: Comant Antennas no longer come with a gasket or template. Must order PN 09-00532 separately.
