The DM NI50 reduces maintenance costs due to its low profile, all-metal blade that provides unequalled mechanical strength and reliability. The NI50 antennas are engineered for use on business, commercial, and military aircraft. NI50 DME antennas can be used will all standard L-Band equipment operating on the 960 MHz to 1,220 MHz frequency band. These antennas are interchangeable with with virtually all L-band blade, flush mountable antennas currently in service on commercial and military aircraft.
This DM NI50 DME/ATC antenna (EDMO# DMNI50-9-2) has a glossy white finish, type TNC male connector, and a four-hole mounting pattern.
