Harxon HX-CH7018A Embedded 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/L2 + L-Band corrections with 2.8dBi gain



The Harxon HX-CH7018A embedded GNSS helix antenna is designed for high precision positioning. Its RTK level positioning accuracy makes it ideal to be integrated into many UAV applications such as surveying, mapping, aerial photography, remote sensing, infrastructure inspection, traffic control and public security.

The HX-CH7018A embedded 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-CH7018A embedded GNSS antenna features a multi-point feeding technology that ensures a high phase center stability with centimeter-level accuracy.

Weighing only 8 g, the lightweight HX-CH7018A embedded antenna is a compact and low power antenna which will allow for longer UAV flight times. This antenna can be easily integrated into UAV solutions to significantly improve the overall reliability and performance.


  • 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
  • 8g, small form factor facilitates easier integration
