DM NI50 antennas, which replace the DM NI49 antennas, are used with all standard L-Band equipment because of their very broad bandwidth of 960 to 1,220 MHz. Models of the DM NI50 antenna are directly interchangeable with virtually all L-Band blade and flush mounting antennas currently in service on commercial and military aircraft. While some replacements will require the use of standard adapter plates which are readily available, none require airframe modification.
The DMNI50-2-4 has Lusterless Black color with male C connector.
- Lusterless black color
- 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
- Low-profile all-metal blade
- Designed for business, commercial and military jet aircraft
