D-Helix™ Antenna HX-CH7609A

Overview

Harxon HX-CH7609A is a high performance GNSS antenna designed for high precision positioning service and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO, BeiDou, as well as L-Band correction service. It could be used for applications as surveying and mapping, and various UAVs operations.

Key Features

High Phase Center Stability for Consistent Performance

The HX-CH7609A D-Helix™ antenna features a multi-point feeding technology that ensures a high phase center stability with centimeter level accuracy as well as adopts D-QHA technology for extraordinary 2.8dBi gain.

Strong Anti-interference Performance

The HX-CH7609A adopts advanced circuit layout and equips a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance and restraints possible unwanted electromagnetic interference.

Optimized Installation for Integration

Weighting only 30.5g, the lightweight HX-CH7609A GNSS antenna has a compact dimension, with diameter 43.6*H40.8mm only. It employs screws mounting at the bottom of the antenna for better steadiness. All these advantages makes it ideal for integrated design.
