DMNI50-6-2 Navigation Antenna
Frequency 960-1220 MHz
(DAI Part# DMNI50-6-2)
Reduced maintenance costs are achieved through the use of this low-profile, all-metal blade as a result of its unequalled mechanical strength and built-in reliability. Currently in use on business, commercial and military jet aircraft, the DMNI50 antennas have clear advantages over the other current designs:

Extremely high side load strength guards against breakage by ground handling gear.
Completely sealed construction prevents failure from moisture intrusion.
Lightning protection circuits prevent damage to antenna and safeguard electronic equipment.

Models of the DMNI50 antenna are directly interchangeable with virtually all L-Band blade and flush mounting antennas currently in service on commercial and military aircraft.
