    ER-MA-08 GNSS Choke Antenna 


    ER-MA-08 GNSS Choke Antenna uses a high-gain wideband antenna to realize the reception of GPS, BDS, GLONASS, Galileo, QZSS and L-Band GNSS signals. The completely symmetrically distributed multi-order 3D choke scheme is adopted to achieve higher phase center stability and extremely superior anti-multipath interference performance. The phase center coincides with the mechanical center, and the performance is superior.
