The 20-40-48 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
