Full-band High-Precision GNSS Antenna
The AH612 GNSS High-Precision Antenna features advanced multi-feedpoint technology and supports L1, L2/L5, and L-band signals across BeiDou, GPS, GLONASS, and GALILEO systems. It integrates multi-stage filtering and a low-noise amplifier to deliver excellent out-of-band signal suppression and strong anti-interference performance. Designed for reliable operation in harsh electromagnetic environments, the AH612 ensures multi-system compatibility and meets the demands of high-precision GNSS positioning applications.
