A high-speed UHF data radio that broadcasts, repeats and receives data used by Trimble GNSS receivers for real-time correction data.
Built to last and extremely versatile, the Trimble TDL450B enhances the accuracy and reliability of positioning in challenging environments, making it ideal for surveying, construction and geospatial applications. It solves signal strength issues and makes the adjustments required to stay productive, even in the toughest conditions.

Broadcasts, repeats and receives real-time data used by Trimble ® GNSS receivers whilst high over-the-air link rate keeps teams productive with less radio downtime.
The TDL450B also provides access to diagnostic data in the field, enabling users to solve signal strength challenges and make adjustments to stay more productive.
• Frequency range – 403–473 MHz
