Q25 GNSS Helical Antenna
Q25 version
Slim and elongated design, compact and lightweight structure
Q39 GNSS Helical Antenna
Q39 version
Wide-body design, stable and reliable signal performance
This series of products is a Quadrifilar Helix antenna in structure, features high gain and wide-angle circular polarization characteristics. Compared to traditional antennas, it can receive more low elevation satellite signals to enhance positioning performance, making it suitable for applications such as smart homes, smart agriculture, and high-precision mapping. It is recommended to purchase SMA Magnetic Mount Antenna Base with 3m extension cable, offering flexible installation and compatibility with various GNSS positioning modules.
