Leica AR20 Future-proof GNSS infrastructure New innovative design choke ring antenna The AR20 is a newly designed 3D GNSS choke ring antenna with variable choke rings for superior tracking performance. The precision design also allows for very low and stable phase centre offsets and very smooth symmetry of the phase centre variations versus azimuth and elevation. More robust for longer durability The newly designed AR20 choke rings are treated with a newer and more robust double treatment for longer lasting durability in all environments. An optional radome cover is also available for added protection....
