Stonex SA1800 GNSS Antenna 3D Choke Ring

Stonex SA1800 3D Choke Ring GNSS Antenna

The SA1800 is Stonex's most advanced and capable geodetic antenna, setting the absolute benchmark for multipath suppression and phase center stability in permanent reference station applications. Its full 3D choke ring design takes multipath reduction to the next level across every GNSS frequency band including L-band, delivering the submillimeter phase center stability demanded by the most exacting CORS networks, structural deformation monitoring programs, and geological survey installations. High gain and wide beam width ensure exceptional low-elevation satellite tracking, keeping signal acquisition strong even in the most obstructed or interference-prone environments such as construction zones, tree lines, and urban settings. The SA1800's LNA provides class-leading out-of-band EMI rejection, protecting receiver integrity against power grids, communication towers, and radio modem interference. Encased in a structurally robust GFRP housing with IP67 protection, it is engineered for the long haul in any climate on earth.
