Description

1. The EA91 uses the total symmetric distribution multi-stage of 3D choke-ring scheme with completely symmetric distribution for higher phase center stability and superior multi-path jamming performance.

2. It has excellent coincidence performance of phase center and mechanical center.

3. Wideband dual-band multi-constellation satellite mode GNSS measuring antenna.

4. Excellent polarization axis ratio performance

5. Excellent phase center performance

6. Excellent anti-multipath jamming performance
