VHF/UHF High Power Airborne Blade Antenna
100 to 500 MHz
The 21-50-21 is an airborne blade capable of accepting high power inputs over the continuous frequency range of 100-500 MHz.
Designed as a modified discone with loss-less matching, the antenna comprises a three dimensional radiating element contained within a one-piece molded radome of glass-epoxy. Attachment to airframe is via a substantial aluminum baseplate with 8 mounting holes making the antenna suitable for transporttype aircraft operating up to Mach 0.85.
