Wide-band VHF/UHF Airborne Blade Antenna
116-174 and 225-400 MHz
The 21-50-64 is a vertically polarized, omni-directional antenna, compatible with airborne transceivers operating within the 116 to 400 MHz frequency range. This antenna is passively matched and requires no external tuning.
This wideband, multi-function antenna developed by Cooper Antennas Ltd provides excellent performance within a small physical package of less than 12 inches in height. Rugged design ensures reliability in world wide conditions of service on helicopters and subsonic aircraft operating up to Mach 0.9
Use of frequency selective matching optimizes efficiency and provides omnidirectional radiation throughout the operating frequency range. Unique element shaping preserves elevation pattern throughout frequency band.
