GSM Airborne Blade Antenna

The 21-40-45-4 is a wide band UHF and C/D airborne blade antenna designed for high performance aircraft covering the GSM frequency band. It is a direct footprint replacement for AT256 UHF Blade antennas.

Electrical design is based on a 2-dimensional, shunt-grounded discone 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 has an aluminum alloy baseplate with a centrally mounted, N-type female coaxial connector.

  • Covers full GSM Band
  • Low profile, diamond shaped blade
  • Designed to meet MIL-STD-810
  • Fully environmentally sealed
  • Grounded for lightning protection
  • Lossless matching - high RF efficiency
  • Omnidirectional radiation pattern
