Harxon HX-CGX611A Mini GNSS Choke Ring Antenna


GPS L1/L2/L5 + GLONASS L1/L2 + BeiDou B1/B2/B3 + Galileo E1/E5ab/E6 + L-band with 52dB Gain



The HX-CGX611A mini GNSS choke ring antenna is only a quarter of the weight of traditional choke ring antennas making it more flexible for multiple applications such as CORS station, Geodetic surveying, Geodetic mapping and other monitoring applications.

The HX-CGX611A is equipped with Harxon’s advanced antenna technology for improved tracking performance. In a 20° elevation, this antenna can still reach -0.5 dB with excellent phase center symmetry and unmatched multipath suppression across all GNSS frequency bands. In addition, the HX-CGX611A’s design offers lightning protection which reaches IEC, GB standard, ensuring the antennas will still perform normally in a thunderstorm.


  • Supports GPS L1/L2/L5, GLONASS L1/L2, BeiDou B1/B2/B3, Galileo E1/E5ab/E6, L-band signals
  • Excellent multipath rejection and low elevation tracking performance
  • Water & dust-proof design
  • Sub-millimeter phase center repeatability
  • LNA has high gain which ensures the operation with long cable (100 meters +)
