AllBand+ Multi-constellation with l-band signals reception This Helix Antenna is a patented multi-constellation antenna, it ensures excellent reception of GPS, Galileo, Beidou, GLONASS as well as L-Band signals in one antenna. Advanced helix technology: This antenna with Helix technology ensures more stable performance of wide-angle circular polarization (WACP), and smaller antenna phase center deviation (PCV), which ensures a more precise positioning accuracy. The innovative technology significantly enhances the low-elevation angle tracking capabilities, extending operation to the entire GNSS constellation. Tracking in challenging environments: This Helix Antenna is able to track any visible satellites under challenging conditions, providing the positioning solutions with higher precision and reliable data. The ability to track low elevation satellites while maintaining high gain makes Helix Antenna an excellent choice for any applications where the sky is partially visible, such as plant protection, tree lines, or for UAV power patrol, GIS surveying where high precision is needed. Strong anti-interference performance: The antenna LNA features an excellent out-of-band rejection performance, which can suppress the electromagnetic interference, providing the stability and reliability of GNSS signals. Also it effectively avoids disconnection dangerous when UAVs are operated under tower and electric power lines. Helix toughest precision antenna: This Helix Antenna is the toughest precision antenna has designed to date, which features the latest low-wind resistance design. Moreover, Helix Antenna features an ultra-durable watertight enclosure, its IP67 ruggedized design can protect it from dust and water.
