AH301H-GNSS Spiral Antenna

Multi-constellation Multi-band L1+L2+L5 Spiral Antenna

 

AH301H GNSS multi-star multi-band spiral antenna adopts multi-arm coupling and four-feed point feeding technology to support L1, L2, L5 dual-band satellite navigation signal reception of Beidou ll, GPS, GLONASS and GALlLE0 systems. With built-in low-noise amplifier, adopting two-stage filter, good out-of-band suppression, and strong anti-jamming ability to ensure the normal work in the harsh electromagnetic environment. lt can meet the current demand for multi-system compatibility and high-precision measurement.
