Overview

Weak signals can flatline productivity

Fill in critical wireless data gaps left by weak signals. Trimble UHF radios provide real-time kinematic (RTK) corrections that ensure positioning accuracy for all your rovers and machines.

Easy field setup and configuration

Built to endure the harsh demands of construction sites

Dial up the power for longer baselines or extend battery life on smaller work sites

Access real-time data in the field and widen your survey reach

Cover more distance and overcome obstacles
