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.
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
During 2021.9.21- 9.23, we will participate in this year's INTERGEO exhibition in Hannover, Germany. Welcome friends who like GPS and surveying to our booth. During this special period, eSurvey will fight the epidemic together with you and share surveying experience, and we look forward to seeing you at Booth 23C.35. Get your free tickets here.
