D-Helix™ antenna HX-CHX602A

The Harxon HX-CHX602A Helix antenna is a multi-constellation and full-frequency high-gain geodetic antenna. Its foldable design allows a bending angle of 90 degrees and provides excellent GNSS signal availability when integrated with survey terminals in the field. It features high sensitivity, low power consumption and compact dimensions, making it ideal for geodetic survey applications.

High phase center stability

The HX-CHX602A supports reliable satellite signal tracking for GPS, GLONASS, Galileo, BeiDou and L-band signals. It provides stable phase center performance with multi-point injection technology, enabling low elevation satellite tracking with high gain and low signal loss. Wide-angle circular polarization (WACP) also improves positioning accuracy.

Tracking in difficult environments

This antenna is capable of tracking visible satellites in challenging environments and providing highly accurate and reliable positioning data. Its ability to track satellites at low elevation makes it ideal for applications where the sky is partially obscured, such as UAV surveillance, GIS surveys and crop protection.

Strong immunity to interference

The advanced Low Noise Amplifier (LNA) improves signal filtering and out-of-band interference suppression, reducing unwanted electromagnetic interference. Multipath rejection across all GNSS frequency bands ensures consistent and reliable GNSS signals even in environments with significant electromagnetic interference, such as power grids and communications base stations.

Compact design with foldable design

The HX-CHX602A features a rugged, compact and foldable design with a bending angle of up to 90 degrees, allowing flexible GNSS signal reception. This design remains reliable even after long-term use. The IP65 waterproof housing ensures long-term performance under harsh environmental conditions such as rain, dust and sunlight.
