Low Profile VHF/UHF Antenna

The 20-50-80 is a wideband discone intended for use as a mast-head mounted VHF/UHF antenna when using its integral radial ground plane, or as a vehicular/ shelter antenna without the radial ground plane when installed on an appropriate conducting surface. The antenna comprises a rugged fiberglass radome containing a specially contoured VHF/UHF discone and associated matching circuits.

All external metalwork is treated aluminum alloy and the removable ground plane has an L-shape bracket to facilitate clamping to the top of a mast.

The entire radome/antenna assembly is foam filled and fully sealed for environmental protection. 

  • Suitable for mast, vehicle and ship installations.
  • Ground plane can be removed for vehicular use.
  • Rugged, fully sealed construction.
  • High efficiency throughout full VHF and UHF communication bands.
  • Designed to MIL-STD-810 Environmental Conditions.
