SA300 High Precision GNSS Antenna

This highly precise micro-centered antenna with an integrated ground plane offers exceptional tracking sensitivity and multipath rejection for all surveying and construction applications. The SA300 antenna supports the GPS and GLONASS satellite constellations’ L1/L2 frequencies.

Dual-Frequency Dual-Constellation Antenna

The SA300 high-precision micro-centered antenna with integrated ground plane provides excellent tracking sensitivity and multipath rejection for all surveying applications. The SA300 antenna supports L1/L2 frequencies from GPS and GLONASS satellite constellations. The SA300 can be paired with applicable Sokkia GNSS receivers to provide a high-performance dual-frequency RTK system.
The SA300 antenna system offers IP67 dust and water resistance as well as superior level of vibration and shock tolerance (IEC 60068-2). With its compact and ultra-rugged design, the SA300 is the most robust antenna in the market today.
