EA45

Geodetic Antenna

The EA45 GNSS antenna has been designed to support millimeter accuracy for land and marine applications. The EA45 GNSS antenna supports present and future GNSS signals, including GPS, GLONASS, BeiDou and Galileo. The EA45 is a survey grade, multi-GNSS precision antenna, ideal for a variety of applications including surveying, RTK positioning and navigation, precision guidance, and machine control. The EA45 antenna can be used in challenging environments (such as near buildings or foliage), as it has superior multipath mitigation, stable phase center and strong SNR’ s even at low elevations. The EA45 aluminum base has been pretreated for a Marine environment and will withstand salt fog and spray. The housing is designed to withstand 2 meter pole drop tests for the antennas.
