Leica AR20 GNSS Antenna
有远见的3D（内部）choke环天线
Leica AR20专为永久和半永久参考网络安装而设计，并满足可靠且持久的天线的所有要求。这是所有GNSS卫星信号的未来证明。
New innovative design choke ring antennaThe AR20 provides superior tracking performance by using different depth and width choke rings. The precision design also allows for very low and stable phase center offsets and very smooth symmetry of the phase center variations versus azimuth and elevation.
Superior multipath performanceWith an excellent axial ratio at low elevations, the AR20 provides results with superior multipath rejection across all GNSS frequency bands including L5, thanks to the new 3D inside design. Traditional 2D choke ring designs are only optimized for a specific frequency band.
Robust for long durabilityThe newly designed AR20 choke rings are treated with a new and robust double treatment for longer lasting durability in all environments. An optional radome cover is also available for added protection.
