DatasheetWide-band VHF/UHF Airborne Blade Antenna
30 to 600 MHz
SKU: 21-50-32
The 21-50-32 is a vertically polarized, omni-directional antenna, compatible with all popular airborne radios operating within the 30 to 600 MHZ frequency range. This antenna can handle up to 100 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 surface deposited radiating element optimizes efficiency and provides omni-directional radiation throughout the operating frequency range. The element is DC grounded for lightning protection. Unique element shaping preserves elevation pattern throughout frequency band.
