Trimble introduced the Trimble® TDL 450H radio, a long-range solution in the Trimble TDL 450 radio modem series designed to support high-precision Global Navigation Satellite System (GNSS) surveying applications. The Trimble TDL 450H is a 2-35 Watt (user programmable) radio transceiver. Its 35 Watts of power maximizes range, enabling work in difficult terrain and urban areas. The multi-function user interface streamlines field configuration and troubleshooting so surveyors can maintain maximum productivity. The radio modem allows users to adapt as conditions require: for longer baselines surveyors can dial up the power, and when the work area is smaller, a lower power output can extend battery life.
