UA91 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.

and all signals (GPS, BDS, GLONASS, GALILEO, IRNSS, QZSS, and SBAS) of GNSS
tracking.
Temperature Performance
The UA91 works in the range of temperatures from -55℃ - to +85℃, and stores in
-55℃ - +90℃.
High Phase Center Accuracy
Experience millimeter phase center accuracy with higher stability
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.
