ER-MA-05 High Quality Drone Antenna
Introduction
The ER-MA-05 High Quality Drone Antenna is a high performance GNSS antenna designed for high precision positioning service and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO and BeiDou. Its RTK level positioning accuracy makes it ideal to be integrated into application as surveying and mapping, and various UAVs operations.
Features
Toughest Precision Antenna: features low-wind resistance design and ultra-durable watertight enclosures. It has IP67 ruggedized design as well as a standard SMA male connector for easy integration.
Strong Anti-interference Performance: The antenna LNA features excellent out-of-band rejection performance, which can suppress the interference of magnetic disturbance, providing the stability and reliability of GNSS signals.
Tracking in Challenging Environments: The ability to track low elevation satellites while maintaining high gain makes this antenna an excellent choice for any applications where the sky is partially visible, such as plant protection, tree canopy, UAV power patrol and GIS surveying.
Advanced D-QHA Technology: D-QHA technology significantly enhances the low-elevation angle tracking capabilities, it ensures more stable performance of wide-angle circular polarization (WACP), and smaller antenna phase center deviation (PCV).
