A25 Survey Grand GNSS Antenna for Land and Marine Applications

This low profile multipurpose antenna has a unique filtering pattern. Precise attention has been paid to mitigation of multipath interference.
 
The A25™ GNSS antenna has been designed to support millimeter accuracy on land and marine applications. The A25 offers support for present and future GNSS signals, including GPS, GLONASS, BeiDou, and Galileo. A25 is a multi-GNSS precision antenna and is ideal for various applications including surveys, single-frequency RTK positioning and navigation, precise guidance, and machine control.
 
This antenna has been designed to excell in challenging environments (such as near buildings and foliage). Itt has superior multipath mitigation, stable phase center and strong SNR’s, even at low elevations. The rugged housing is made of an aluminum base that has been pretreated for the marine environment and will withstand salt, fog, and spray.
 
The A25 antenna easily passes the two-meter pole drop test.
