Description

This compact snap-in mount module antenna is designed for high-precision GNSS applications, supporting GPS, GLONASS, BeiDou, QZSS, and Galileo systems. With a pre-filter and 28 dB active gain, it delivers excellent signal quality and low noise performance, making it ideal for integration into consumer electronics, robotics, drones, fleet management, and other location-based solutions. Its ground plane independence and low power consumption further enhance its suitability for embedded and portable devices.
