UHF Antenna

The 20-30-200 consists of a high strength, low loss cylindrical glass/epoxy radome containing a vertical array of four co-linearly stacked dipoles combined in such a way as to maximize radiation in the horizontal plane (0° elevation).

The array is end-fed enabling the antenna to be ground-plane independent.

The entire assembly is foam filled for long term environmental protection. It has an N type (female) connector and a 3 inch diameter metal fitting to enable mast-head mounting.  

  • Suitable for mast head mount
  • Pattern optimized for highest gain at horizon
  • Rugged design for MIL-STD-810 environment
  • High power 200 Watts CW
  • Hi gain (+7 dBi typical)
