This is a new (old) surplus item and has been in storage at our aircraft parts supply store.
It comes in the original box, with the gasket, never used.
Frequencies Covered: 118-137 MHz
Similar to the CI 109, the CI 121 is smaller in diameter and lighter at only 0.5 pounds. Features a tapered glass laminate housing and die-cast aluminum base. Offers standard mounting and appearance to many Cessna communication antennas. The CI 121 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: Gasket included.
