DM C70-3 VHF Communications Antenna
Frequency 118-137 MHz
(DAI Part# DMC70-3)
The DM C70 series VHF Communication Antennas are designed for top or bottom installation on high-performance, single, twin and turbo engine fixed and rotary wing aircraft. These uniquely designed antennas offer mechanical strength and high-electrical efficiency to provide maximum reliability and full 360/720 channel transceiver operation. The lightweight profile is unobtrusive, resists icing and offers low drag.

The DM C70-3 is directly interchangeable with the following part numbers: C598501-0104, VF 10-210, CI 109, and CI 121.

The DM C70-4 which supersedes the DM C70-2, is specifically designed for bottom installations, where ground clearance does not permit the use of other DM C70 series antennas. The DM C70-4 provides a higher degree of efficiency to assure maximum performance from your transceiver.

The DM C70-6, and DM C70-9 variants of the DM C70-1/A, have a different mounting hole pattern and connector location. All other characteristics remain the same.
