Ultra-low Power Multi-constellation Multi-band Spiral Antenna
AH201a GNSS antenna, with dobby coupling and four-feedpoint feed technology, ultra-low power consumption, supports L1 and L5 dual-band satellite navigation signal reception of BeiDou II, GPS, GLONASS and GALILEO systems, built-in low noise amplifier, two-stage filter, good out-of-band suppression, and strong anti-jamming ability to ensure normal operation in harsh electromagnetic environments. Meet the current demand for multi-system compatibility and high-precision measurement.
