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 that will keep you working with complete confidence. The full-function user interface streamlines field configuration and troubleshooting so you can maintain maximum productivity. Adapt as conditions require: for longer baselines you can dial up the power, and when the work area is smaller, a lower-power outputextends battery life. The Trimble TDL 450 series even provides access to diagnostic data in the field. So, you can solve signal strength challenges and make adjustments to stay more productive.
