DM N25 Center-Fed Loop Antenna | 329–335.3 MHz, Dual output, C

Product Description

The DM N25 Series of glide slope antennas employ a grounded, center-fed loop as the radiating element. The resulting radiation patterns are symmetrical. All DM N25 Series antennas provide complete lightning protection for the associated receivers. They are suitable for mounting either externally, or within a nose radome. The inherent 180° pattern beam may be modified slightly by the geometry surrounding the installation. The DM N25 antennas are recommended for installations in close proximity to radar dish installations since the antenna’s (glide slope) sensitivity is relatively unaffected by dish motion.

The DM N25-2 is a dual connector version which incorporates a hybrid. The circuitry isolates the two associated receiving systems providing protection against disablement of both systems in the event of failure in one system.
