DM N25 Glide Slope Antenna | 329–335.3MHz, TNCf Connector

The DM N25 series glide slope antennas use a grounded, center-fed loop as its radiating element, resulting in a symmetrical radiation pattern. The N25 GS antennas provide complete lightning protection for associated receivers. These antennas can be mount either externally or inside a nose radome, even though its 180° degree bean pattern may be slight altered by the antenna's installation surroundings. Recommended installation of the N25 antenna is within close proximity to a radar dish installation since the glide slope sensitivity is relativity unaffected by dish motion.
 

This DM N25 glide slope antenna (EDMO# DM N25-1) has a TNC female connector.
