Stonex SA1100 GNSS Antenna Mini Choke Ring

Stonex SA1100 GNSS Mini Choke Ring Antenna

When submillimeter precision is the standard, the SA1100 delivers. This compact Mini Choke Ring antenna is engineered for the most demanding GNSS applications, including permanent CORS networks, structural monitoring, and geodetic infrastructure projects where phase center stability is non-negotiable. Its unique ring structure provides outstanding multipath suppression across all frequency bands, while its high gain performance ensures reliable signal acquisition even at low elevations in obstructed or challenging environments. Tracking all major satellite constellations including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS, and L-band correction services, the SA1100 offers comprehensive global coverage. Despite its choke ring design, it is significantly more compact and lighter than standard choke ring antennas at just 185mm diameter and 1.9kg, making installation straightforward without sacrificing an ounce of performance. NGS and IGS calibrated, IP67 rated, and built to operate across extreme temperatures, this is a reference-grade antenna ready for permanent deployment anywhere in the world.
