Harxon HX-CH7609A GNSS Helix Antenna


GPS L1/L2/L5 + GLONASS L1/L2 + Galileo E1/E5a/E5b + BeiDou B1/B2/B3 + QZSS L1/L2/L5/L6 + IRNSS L5 + SBAS L1/L5 + L-band with 33 dB Gain



The Harxon HX-CH7609A is a high performance GNSS helix antenna designed for precision positioning. It can be used for many UAV applications such as surveying, mapping, aerial photography, remote sensing, infrastructure inspection, traffic control and public security.

The HX-CH7609A helix antenna adopts patented D-QHA technology for stable performance of wide-angle circular polarization (WACP), which ensures exceptional low elevation satellite tracking while maintaining high gain and providing reliable signal tracking. This consistent performance makes it an ideal option for UAVs even under challenging environments.

The HX-CH7609A GNSS antenna features a multi-point feeding technology that ensures a high phase center stability with centimeter-level accuracy.

Weighting only 30.5 g, the lightweight HX-CH7609A GNSS antenna is compact which will allow for longer UAV flight times.


  • Comprehensive GNSS support: GPS, GLONASS, Galileo, BeiDou, as well as L-Band correction service
  • Centimeter phase center repeatability, high gain at low elevation
  • Improved signal filtering and excellent multipath rejection
  • Lightweight, low profile for easy integration
