DATASHEET:
Overview
The Harxon HX-CH7603A GNSS UAV/helix antenna utilizes Harxon’s D-QHA technology which significantly enhances the low-elevation angle tracking capabilities. Wide-angle circular polarization (WACP) and small antenna phase center deviation (PCV) help to ensure stable performance and accurate positioning even in the most challenging environments.
The ability to track low elevation satellites while maintaining high gain makes the HX-CH7603A antenna an excellent choice for any application where the sky is partially visible.
The antenna LNA features excellent out-of-band rejection performance, which can suppress electromagnetic interference, providing the stability and reliability of GNSS signals.
The HX-CH7603A UAV/Helix antenna is the toughest precision antenna Harxon has designed to date. It features the latest low-wind resistance design and ultra-durable watertight enclosures. Its IP67 rated ruggedized design means it is protected from dust and water.
Features
- Supports GPS, GLONASS, Beidou signal reception
