Trimble has introduced the TDL 450H radio, a long-range radio in the Trimble TDL 450 radio modem series designed to support high-precision 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, Trimble said.

According to Trimble, 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.

The Trimble TDL 450 series offers flexible field configuration options and rugged reliability, Trimble said. The series is available in two frequency bands to cover the entire commercial UHF band without sacrificing radio performance. It also allows the user to select from either 12.5 or 25 kHz channel bandwidth.This high-power radio comes with a new protocol offering 9600 bps in a 12.5 kHz channel without loss of range.

The Trimble TDL 450 series is an advanced, high-speed, wireless UHF data radio built to endure the stresses of daily use in harsh conditions. Full metal construction provides impact and weather resistance. The Trimble TDL 450 series also provides access to diagnostic data in the field, allowing surveyors to solve signal strength challenges and make real-time adjustments to stay more productive.
