Hemisphere A45 GNSS Survey Grade Antenna, Multi-GNSS Precision Antenna

Like the A25, the Hemisphere A45 GNSS antenna has been designed to support millimeter accuracy for land and marine applications, but the A45 also supports present and future GNSS signals (GPS, GLONASS, BeiDou, QZSS, and Galileo) at the multi-frequency level.
The A45 multi-GNSS precision antenna is ideal for various applications including surveys, RTK positioning and navigation, precise guidance, and machine control. The A45 antenna can be used in challenging environments (such as near buildings and foliage) as it is designed for multipath mitigation, stable phase center, and strong SNRs, even at low elevations.
The ruggedized housing is made of an aluminum base that has been pretreated for the marine environment and will withstand salt, fog, and spray.
This antenna easily passes the two-meter pole drop test.
