2122 Trimble is widening its radio line-up with the addition of the TDL450H for surveyors. This unit offers long-range capabilities for productive surveys and is designed to support high-precision GNSS surveying applications. The Trimble TDL450H is a 2-35W radio transceiver and enables work in difficult terrain and urban areas. The multi-function user interface streamlines field configuration and troubleshooting so surveyors can maintain 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 TDL450 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 25kHz channel bandwidth. This high-power radio comes with a new protocol offering 9600bps in a 12.5kHz channel without loss of range.
