Harxon HX-CH3602A GNSS UAV/Helix Antenna


GPS L1 + GLONASS L1 + BeiDou B1 with 36 dB Gain



The Harxon HX-CH3602A GNSS UAV/helix antenna utilizes Harxon’s QHA technology, wide-angle circular polarization (WACP) and small antenna phase center deviation (PCV) to ensure stable performance and accurate positioning even in the most challenging environments.

The antenna LNA features excellent out-of-band rejection performance, which can suppress electromagnetic interference, providing stability and reliability of GNSS signals.

The HX-CH3602A antenna is small and lightweight, making it ideal for UAV applications, and its standard SMA male connector allows for easy integration. The ruggedized design of this antenna has an IP65 rating for dust and water protection.


  • Supports GPS, GLONASS and BeiDou signal reception
  • Stable phase center guarantees the accuracy of positioning within millimeter level
  • Anti-interference capability to endure the harsh operating environments
  • IP65
