UA91 adopts high-gain broad band antenna covering GPS, GLONASS, BDS, Galileo, QZSS and L-Band with fully symmetrically distributed multi-level 3D choke-ring solution to achieve better phase center stability and excellent anti-multipath performance. The antenna has excellent performance of overlapping phase center and machine center.
- Broadband dual-frequency multi-system GNSS survey and mapping antenna
- Polarization axis ratio performance
- Good performance of phase center
- Good performance of anti-multipath
