Comant CI-211

Overview

Optimum antenna for high-performance jet aircraft. Only 8.25" high, yet provides good performance without the added drag of a taller blade-type communication antenna. Skydrol and rain erosion resistant. The optional CI 211-L offers leading edge protection as shown in outline drawing. The CI 211 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.
