S/C Band Airborne Blade Antenna

The 21-40-37 is a wide frequency S/C band airborne blade antenna designed for fixed and rotary wing aircraft. It is a direct footprint replacement for AT256 UHF Blade antennas.

Electrical design is based on a 2-dimensional, monocone which is of high efficiency and provides nearly omnidirectional azimuthal radiation.

Mechanical design uses an advanced, glass-loaded thermoplastic radome with an integral radiating element, all foamed-in-place for structural and environmental integrity.

The blade is built into a contoured injection moulded base collar and has a centrally mounted, N-type female coaxial connector. 

  • Covers wireless and datalink frequencies from 2.4 to 5.9 GHz
  • Low profile, diamond shaped blade
  • Designed to meet MIL-STD-810
  • Fully Environmentally sealed
  • Lossless matching - high RF efficiency
  • Nominally omnidirectional radiation pattern
