CR3 G3
CR3 G3
● The South CR-3 UHG provides a stable phase center offsets
at sub-millimeter 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
