D-Helix™ antenna HX-CHX600A

The Harxon D-Helix™ antenna is a patented D-QHA multi-constellation antenna that provides excellent reception performance for GPS, Galileo, BeiDou, GLONASS and L-band signals in a single antenna.

Advanced D-QHA technology

Harxon's D-QHA technology provides more stable performance at wide-angle circular polarization (WACP) and lower antenna phase center (PCV) deviation, ensuring more precise positioning accuracy. This innovative technology significantly improves the ability to track satellites at low elevation angles and enables operation across the entire GNSS constellation spectrum.

Tracking in difficult environments

The D-Helix™ antenna can track visible satellites even in difficult conditions, providing more precise positioning solutions with reliable data. Its ability to track low elevation satellites with high gain at the zenith makes it ideal for applications where the sky is partially obscured, such as crop protection, tree rows, UAV monitoring and GIS surveys.

Strong immunity to interference

The antenna's LNA provides excellent out-of-band noise rejection and suppresses electromagnetic interference, ensuring the stability and reliability of GNSS signals and preventing signal interruptions when UAVs operate near towers and power lines.

Harxon's most robust precision antenna

The D-Helix™ antenna is Harxon's most robust precision antenna yet, with a design that offers low wind resistance and an extremely durable waterproof housing. Its IP67-rated rugged design protects it from dust and water.
