High Power Broadband Airborne Blade Antenna

The 21-50-97-1 is vertically polarized, omni-directional antenna, compatible with all popular airborne radios operating within the 30 to 520 MHz frequency range. The antenna can handle 160 Watts of power, requires no external tuning and is designed as a high power, extended frequency coverage antenna to operate with latest JTRS radios.

This wideband multifunction antenna is particularly suited to tactical military communications and jamming. 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.
