Trimble Zepyhr 3 Base Antenna

Manufacturer: | Category:

The Zepyhr 3 Base antenna from Trimble is a robust, high performance antenna with advanced technology for multipath reduction. Its stainless steel mounting allows the antenna to be used in the most rugged of environments.



The Zepyhr 3 Base antenna from Trimble is ideal for all base station applications. It contains advance technology for excellent outstanding low elevation satellite tracking.

The Zepyhr 3 Base antenna offers support for present and future GNSS signals, including GPS, GLONASS, BeiDou and Galileo. This ensures the operation of your antenna with your present and future GNSS receivers. It also supports L-Band signal reception, OmniSTAR, Trimble RTX and SABS.

Its unique design ensures high multi-path signal rejection, which prevents inaccurate measurements making it suitable as a fixed rover antenna for use in high multi-path environments. Sub-millimeter phase center repeatability ensures Zephyr 3 Base antenna’s quality performance and extreme accuracy. Advanced filtering with additional Iridium and Japanese LTE filtering keeps the GNSS measurements safe from unwanted interference.
