UA35
GNSS Antenna
The UA35 covers the reception of GNSS signals such as GPS, GLONASS, BDS, Galileo, QZSS, IRNSS and L-Band. It has the superior performance of the antenna phase center. Its small size and light weight make it easy to carry around and operate.

Powerful Satellite Tracking Capacity
Obtain all available and reliable data sources, with total channels and all signals (GPS, BDS, GLONASS, GALILEO, IRNSS, QZSS, and SBAS) of GNSS tracking.

High Gain (GPS L1 > 6 dBi, GPS L2 > 5 dBi)
No longer worry about the effect of experiencing strong GNSS satellite tracking ability, and make your measurement work and data more reliable due to the excellent antenna gain.

Superior Antenna Phase Center
Further, improve the reliability of your measurement work due to the coincidence of the phase center and mechanical center that can make the phase center error less than 2 mm.

Rugged Design
Use it for many years with IP69K design that is protected against the ingress of dust and high temperature, high-pressure water - making products with this certification ideal for use in conditions where equipment must be carefully sanitized.).

Small size and Light Weight
Easily carry it in a variety of complex environments.

Excellent Axial Ratio Performance
Axial ratio ≤6 dBi makes the UA35 antenna performance better.
