The eSurvey UA91 adopts a high-gain broadband antenna to receive GNSS signals such as GPS, BDS, GLONASS, Galileo, IRNSS, QZSS, and L-Band. The scheme of multi-stage 3D choke coils with a symmetrical distribution is adopted to achieve higher phase center stability and excellent anti-multipath interference performance. It has excellent performance and the phase center coincides with the mechanical center.

Rugged Design for Harsh Environments
Use it for many years with IP67 design, which is 95% protected against solid objects like dust and sand, and it has been tested to work for at least 30 minutes under 15 cm to 1 m of water.
Excellent Multipath Suppression Effect
Due to the unique 3D choke coil design and electrostatic protection against eight kv of air and four kv of static electricity, no longer a need to worry about interference by multipath.
High Gain
The UA91 uses a high-gain wide-band dual-band multimode GNSS measuring antenna to achieve coverage of the GNSS signal reception.
