Trimble Zephyr 3 Rover Antenna

The Trimble Zephyr™ 3 Rover Antenna is a top-of-the-range, lightweight GNSS rover antenna engineered for precision RTK and roving applications. Designed with advanced multipath reduction technology, robust low-elevation satellite tracking, and millimeter phase center repeatability, the Zephyr 3 delivers the stable, repeatable performance required for high-accuracy survey workflows.

Offering comprehensive support for current and emerging GNSS signals—including GPS modernization, GLONASS, Galileo, BeiDou, QZSS, IRNSS, OmniSTAR, Trimble RTX™, and SBAS—the Zephyr 3 is built to maximize signal availability and reliability. With a four-point antenna feed, advanced LNA design, and 50 dB signal gain, it ensures consistent tracking performance even in challenging environments. The fully sealed, IP67-rated housing and 5/8”-11 stainless steel mount make it ideal for demanding field conditions.
