The C70 Series VHF Communication Antennas are designed to be installed on the top or bottom 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. Its lightweight profile is unobtrusive, resists icing, and has low drag.

This C70 series VHF communication antenna (EDMO# DM C70-4) has a has 4-hole mounting pattern, centered BNC connector, and a 2.58 x 4.26 inch footprint.

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

Features

• 118 MHz – 137 MHz frequency range
• 2.0:1 VSWR
