EA91

Choke Ring Antenna
EA91 adopts high-gain broadband antenna to receive GNSS signals such as GPS, BDS, GLONASS, Galileo, QZSS and L-Band. The scheme of multi-stage 3D choke coils with completely symmetrical distribution is adopted to achieve higher phase center stability and excellent anti-multipath interference performance. It has excellent performance that the phase center coincides with the mechanical center.
