Key Features

Multiple-constellation with L-Band Signal Reception

The Harxon D-Helix™ Antenna is a patented D-QHA multi-constellation antenna, it ensures excellent reception of GPS, Galileo, Beidou, GLONASS as well as L-Band signals in one antenna.
Advanced D-QHA Technology

Harxon’s D-QHA technology ensures more stable performance of wide-angle circular polarization (WACP), and smaller antenna phase center deviation (PCV), which ensures a more precise positioning accuracy.
Tracking in Challenging Environments

The D-Helix™ Antenna is able to track any visible satellites under challenging conditions, providing the positioning solutions with higher precision and reliable data.
Strong Anti-interference Performance

The antenna LNA features an excellent out-of-band rejection performance, which can suppress the electromagnetic interference, providing the stability and reliability of GNSS signals.
Harxon's Toughest Precision Antenna

Harxon’s D-QHA technology ensures more stable performance of wide-angle circular polarization (WACP), and smaller antenna phase center deviation (PCV), which ensures a more precise positioning accuracy.
