Wideband Airborne and Vehicular Antenna

The 20-40-47 is an ultra wideband, monopole antenna suitable for airborne and vehicular applications, designed for use in datalink applications. The antenna structure comprises a unique element design with careful element shaping to optimize radiation diagram and avoid deep nulls in the elevation pattern throughout the band.

Construction is from high strength fibre glass with aluminium alloy base plate and the whole structure is filled with closed cell foam for long term reliability in world wide conditions of service. 

  • Ultra wide-bandwidth
  • Low profile
  • Can be used in arrays
  • Fully sealed construction for environmental reliability
  • Designed to MIL-STD-810 Environmental conditions
  • 100 Watts power handling
