The SA1100 Mini Choke Ring GNSS Antenna delivers high-precision satellite tracking in a compact, rugged form factor. Supporting all major constellations—including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS, and L-Band correction services—this multi-frequency antenna ensures stable, accurate positioning for demanding professional applications.
With a unique choke ring structure, the SA1100 offers superior multipath suppression and submillimeter phase center stability, making it ideal for monitoring networks, CORS stations, and GNSS infrastructure projects. It maintains high gain performance, even when receiving low elevation signals, which is crucial in obstructed or urban environments.
The SA1100 is lightweight (1.9 kg) and compact (185 mm diameter)—much smaller and easier to install than standard choke ring antennas. Its IP67-rated enclosure protects the internals from dust, water, and tough site conditions, offering long-term durability in any environment.
