HX-CHX600A UAV Helix Antenna

Harxon HX-CHX600A D-Helix Antenna

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



The Harxon HX-CHX600A D-Helix Antenna is an innovative antenna capable of superior tracking for GPS (L1/L2/L5/L-band), GLONASS (G1/G2/G3), Galileo (E5a/E5b/E6/E1) and BeiDou (B1/B2/B3) signals. The 4dBi high gain and wide beam width ensures a better signal receiving performance of satellites at low elevation angle. The innovative dual quadrifilar helix antenna (D-QHA) technology provides a stable phase centre. The low noise figure enhances transmission interference reduction and improves signal quality.

The HX-CHX600 antenna’s IP67 rated ruggedized design means it is protected from dust and water. The low wind-resistance design in a small and lightweight form factor makes it ideal for UAV positioning and navigation. The standard SMA male connector allows for easy integration.

The HX-CHX600A antenna can be used in various UAV applications providing centimetre-level positioning accuracy for a stable flightpath, reliable positioning and heading information.


  • Supports GPS, GLONASS, Galileo, BeiDou and L-Band
  • D-QHA technology ensures an exceptional low elevation satellite tracking
  • Stable phase center guarantees accurate positioning
  • Strong anti-interference ability to endure the harshest operating environments
