Stonex SA1500 GNSS Antenna 2D Choke Ring

Stonex SA1500 2D Choke Ring GNSS Antenna

The SA1500 represents the pinnacle of Stonex's geodetic antenna lineup, engineered for the most precision-critical permanent installations where nothing less than submillimeter performance will do. Its unique 2D choke ring design delivers outstanding multipath suppression across every GNSS frequency band including L-band, making it the definitive choice for CORS stations, bridge and structural deformation monitoring, and geological surveillance networks. The SA1500's LNA provides exceptional out-of-band rejection, actively suppressing electromagnetic interference from power grids, communication towers, and radio modem systems to keep signal integrity ironclad. High gain and wide beam width ensure reliable tracking of low-elevation satellites even in complex, obstructed environments such as construction zones or tree-lined sites. Constructed from Glass Fiber Reinforced Polymer for structural strength and finished with an IP67-rated cover, the SA1500 is built to endure permanent outdoor deployment across the most extreme temperature ranges on the planet.
