TDL 450b

The Trimble TDL450B UHF Data Radio delivers reliable, high-performance wireless communication for RTK-enabled GNSS systems—ideal for demanding geospatial, surveying, and construction environments.

Key Features & Benefits:

• High-speed link performance: Supports 4,800–19,200 bps over-the-air rates with both 4FSK and GMSK modulation, enabling smooth, real-time 1 Hz RTK correction data transmission

• Flexible output power: User-selectable transmit levels from 1 W to 35 W (region dependent) tackle varied jobsite sizes and baseline distances

• Rugged reliability: Full-metal MIL‑STD‑810H enclosure with IP67 ingress protection ensures uptime across dust, rain, heat/cold extremes (–30 °C to +65 °C / –20 °F to +150 °F)

• Advanced connectivity: Built-in Bluetooth support simplifies setup by eliminating serial cables, while on-device keypad and OLED display offer fast field configuration with diagnostics

• Versatile mounting: Compact design mounts directly on GNSS receiver tripods or standalone tripods, ideal for flexible base, rover, or repeater roles

• Seamless ecosystem integration: Works with Trimble and third-party GNSS receivers and supports multiple link protocols (TrimTalk, PCC, SATEL), ensuring compatibility across mixed fleets
