Frequency · 118-137 MHz 

Identical to the CI-119 with the exception of the mounting hole pattern and RF connector location which are compatible with Beechcraft mounting.

RF connector is offset from the centerline of the antenna.

The CI-138 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.
