Trimble Zephyr 3 Geodetic antenna bringing the next generation of signal reception quality to the already proven GNSS Zephyr Geodetic 2 design. By improving upon the signal reception characteristics, the Zephyr 3 Geodetic antenna greatly improves performance in harsh signal environments.

Consistently delivering phase-center eccentricities of less than 1 mm, the Zephyr 3 Geodetic antenna’s performance guarantees that even in a large network, all stations will be capable of delivering accurate, repeatable measurements.

Trimble Stealth™ ground plane - this resistive ground plane consumes unwanted signals before they can reach the receiving element and corrupt measurements. Yet another benefit of the Stealth ground plane is its frequency independent performance. It mitigates unwanted signals throughout the rapidly-expanding GNSS spectrum.
