DatasheetBroadband Airborne Blade Antennas
30 to 400 MHz
SKU: 21-50-92
The 21-50-91/92/93 are vertically polarized, omni-directional antennas, compatible with all popular airborne radios operating within the 30 to 400 MHz frequency range. These antennas can handle 100 Watts of power and require no external tuning.
These wideband, multi-function antennas developed by Cooper Antennas Ltd are particularly suited to tactical military communications. Rugged design ensures reliability in world wide conditions of service on aircraft operating at speeds up to Mach 1.0.
Use of a surface deposited radiating element optimizes efficiency. The element is DC grounded for lightning protection.
