The full-band four-arm helical GNSS antenna is a high-performance satellite antenna that integrates multi-system compatibility and high-precision positioning features. It adopts a four-arm symmetrical helical structure design and achieves high-purity right-hand circular polarization radiation through precise 90° phase progressive feeding technology, which naturally matches the satellite navigation signals and significantly reduces polarization mismatch losses.

The product covers the full frequency bands of the global mainstream GNSS systems such as Beidou (BDS), GPS, GLONASS, and Galileo, including core frequency bands BDS B1/B2/B3, GPS L1/L2/L5, GLONASS G1/G2/G3, and Galileo E1/E5a/E5b. It has a wide frequency coverage range and can form a redundant positioning network to e ...
