Choke Ring GNSS Antenna
- The South CR-3 UHG provides a stable phase centre offsets at sub-millimetre level to guarantee your reference station an excellent tracking performance.
- Choke rings design inside the antenna helps achieve an outstanding multipath rejection performance.
- High-gain design for low elevation tracking enhances signal availability for more satellites.
- Ultralow line loss on signal transmissions, enables connecting cable extend more than 100 meters carrying undamaged signals.
- Fully sealed core components, waterproof and dustproof design, make it withstand severe conditions for continuous work in the field
