DatasheetUltra Wide-band VHF/UHF Airborne Blade Antenna
30 to 2000 MHz
SKU: 21-50-100A
The 21-50-100A is a vertically polarized, omni-directional antenna, compatible with all popular airborne radios operating within the 30 to 2000 MHz frequency range. This antenna can handle up to 50 Watts of power and requires no external tuning.
This wideband, multi-function antenna developed by Cooper Antennas Ltd is particularly suited to tactical military communications. Rugged design ensures reliability in world wide conditions of service on helicopters and subsonic aircraft.
Use of a top loading disc increases gain in VHF whilst not corrupting higher frequencies. Unique element shaping preserves elevation pattern throughout frequency band.
