L/S Band Airborne Blade Antenna

The 21-40-07 is an L/S band airborne blade antenna designed for high performance aircraft. It is a direct footprint replacement for AT256 UHF Blade antennas.

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 has an aluminum alloy baseplate with a centrally mounted, TNC female coaxial connector.

Different base configurations can be provided. 

  • Suitable for supersonic aircraft up to Mach 2.5
  • Low profile, diamond shaped blade
  • Designed to meet MIL-STD-810
  • Fully Environmentally sealed
  • Lossless matching - high RF efficiency
  • Omnidirectional radiation pattern
  • Foamed in place radiating element
