The NI50 is currently in use on business, commercial and military aircraft. They have clear advantages over other current designs including:
- 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.
NI50 Antennas, which replace the NI49 Antennas, are used with all standard L-band equipment because of their broad bandwidth of 960 to 1,220 megahertz. Models of the NI50 Antenna are directly interchangeable with virtually all L-band blade and flush mounting antennas currently in service on commercial and military aircraft.
