The Leica AR20 is a new innovative design antenna that brings new levels of performance for reference station and monitoring applications. The AR20 contains a new 3D design choke ring for improved tracking performance, excellent phase centre symmetry and unmatched multipath suppression across all GNSS frequency bands.
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.
Additional Power Surge Protection
The innovative integrated multi-stage power surge arrestor for the AR20 enhances protection against power surges in the electrical system, typically caused by lightning or any other source of high voltage.
Superior Multipath Performance
The AR20 has excellent Axial Ratio at low elevations which results in superior multipath rejection across all GNSS frequency bands including L5, due to the new 3D (inside) design. Traditional 2D choke ring designs are typically optimised for a single frequency band, while the AR20 has been optimised for superior multipath performance across all GNSS frequency bands.
