DM NI70-2 DME/ATC Transponder Antenna | 950MHz–1220MHz, 4-Hole Mount, BNC Female Connector

The NI70 L-Band transponder antenna provides sufficient bandwidth for DME and ATC frequencies on civil aviation aircraft. It will provide omni-directional, vertically polarized coverage when installed on the top or the bottom of an aircraft. To reduce drag, this antenna features an aerodynamic designed structure that consists of a single metal element.

This DM NI70 transponder antenna (NI70-2) has a BNC female connector and a four-hole mounting pattern.

Features

• 950 MHz – 1,220 MHz frequency range
