Multi-feed point design and fully symmetrical antenna structure, with a very stable phase center, reducing the measurement error of the antenna pair.

The gain is high, the standing wave ratio is low, and the effect of receiving low-elevation signals is obvious, and the star can be received normally in the occasion of severe occlusion.

Equipped with anti-multipath choke plate, with anti-surge design, which can effectively suppress strong interference signals outside the band to ensure the reliability of the antenna.

Using anti-ultraviolet PC material design, which is both beautiful and ensures that the antenna shell will not change color for a long time outdoor use. It has IP67 waterproof rating, high temperature resistance, sun protection and UV protection

This antenna covers the four-star multi-frequency external flying saucer antenna of GPS L1/L2/L5, GLONASS L1/L2/L3, BDS B1/B2/B3, GALILEO E1/E5a/E5b/E6, SBAS L1/L5 QZSS L1/L2/L5/L6, IRNSS L5, L-Band which meets the needs of multi-system compatible and high-precision users of current GNSS measuring equipment. It is widely used in geodesy surveying, navigation surveying, navigation, precision agriculture and marine surveying. It can also be applied to the military field according to the application conditions.
