Introduction

The Harxon HX-CH7609A is a high-performance GNSS antenna designed for high-precision positioning applications, supporting GPS, GLONASS, Galileo, BeiDou, and L-band correction services. It delivers stable satellite tracking and reliable positioning accuracy in dynamic environments. Optimized for surveying and mapping as well as UAV and drone operations, the HX-CH7609A combines robust RF performance with a compact, field-ready design, making it suitable for both ground-based and airborne precision positioning systems.

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.
