ATC/SSR Antenna

The 20-40-72 consists of a high strength, low loss cylindrical glass/epoxy radome containing a vertical array of four colinearly 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 1 inch diameter metal fitting to enable mast-head mounting. 

  • Covers civilian SSR (Secondary Surveillance Radar) / ATC (Air Traffic Control) requirement 
  • Supplied with base spigot for mast head mount
  • Pattern optimized for highest gain at horizon
  • Rugged design for all weather operation
  • At least 50 Watts CW
  • Approximately 5.5 pounds weight
