    ER-MA-01 Small Measurement Antenna


    ER-MA-01 Small Measurement Antenna is a miniaturized multi-system dual-frequency GNSS antenna with a compact design that supports the reception of such as GPS, BDS, GLONASS, Galileo, and QZSS. It also supports L-Band signal reception. The GNSS signals antenna housing uses a cast aluminum base, which meets the requirements of high-strength environmental applications, including salt spray and seawater spray in marine environments. The antenna can be installed through the M18 through the wall, or you can use the base to connect to the device. The product can be used in high-precision applications such as autonomous driving and drones.
