Harxon HX-GG486A GNSS Choke Ring Antenna


GPS L1/L2 + GLONASS L1/L2 with 50dB Gain



The HX-GG486A GNSS choke ring antenna receives GPS and GLONASS frequencies with a integrated radome, which contains Harxon advanced antenna technology. It has become the preferred product for CORS station and geodetic base station applications.

The HX-GG486A’s unique wideband antenna technology design provides superior low elevation satellite tracking, multipath reduction and sub-millimeter phase center stability. The new low noise amplifier (LNA) is used to provide exceptional low measurement noise for superior measurement quality with excellent out of band rejection. The new LNA technology also has high gain which ensures the operation with long cable (100 meters +).


  • Supports GPS L1/L2, GLONASS L1/L2 signals
  • Ideal for fixed reference stations and GNSS infrastructure networks
  • Water & dust-proof design
  • Sub-millimeter phase center repeatability
  • LNA has high gain which ensures the operation with long cable (100 meters +)
