DatasheetBroadband Airborne Blade Antenna
30 to 512 MHz & 960 to 1220 MHz
SKU: 21-50-156
The 21-50-156 is a high speed passive blade antenna providing full VHF, UHF and L-band performance in a double raked, low RCS design. It is compatible with all airborne radios operating within the 30 to 512 MHz frequency range plus Link16, Tacan, IFF, JTIDS and other L-band systems.
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 aircraft operating at speeds in excess of Mach 1.0.
The element is DC grounded for high voltage transfer protection.
