DatasheetBroadband Airborne Blade Antenna
100 to 530 MHz
SKU: 21-50-99
The 21-50-99 is vertically polarized, omni-directional antennas, compatible with all popular airborne radios operating within the 100 to 530 MHz frequency range. The antenna can handle 75 Watts of power and requires no external tuning.
This wideband multifunction antenna developed by Cooper Antennas Ltd is particularly suited to tactical military communications. Rugged design ensures reliability in world wide conditions of service on aircraft operating at speeds up to Mach 0.95.
Use of a surface deposited radiating element optimizes efficiency and the radiating element is DC grounded for static protection..
