Wideband Airborne Antenna
225 to 2500 MHz
The 21-50-106 is a wideband, passive monopole antenna suitable for airborne and vehicular applications. The antenna structure comprises a unique element design with careful element shaping to provide excellent gain and radiation, particularly in the important 0º to 30º elevation sector.
Construction comprises shaped internal aluminium alloy element contained within a circular woven glass-epoxy radome, fully sealed and filled with closed cell foam for long term reliability in world wide conditions of service.
- Ultra wide-bandwidth
- Continuous frequency coverage
- Fully sealed construction for environmental reliability
- Designed to MIL-STD-810 Environmental conditions
- Can handle up to 200 watts CW
