Trimble TDL 450H 430-473 MHz Radio Modem

Trimble TDL 450H 430-473 MHz

Trimble TDL 450H Radio
Designed to support all aspects of GNSS surveying,
the Trimble® TDL 450 series offers flexible
configuration options and rugged reliability. This
sophisticated radio modem places Trimble’s newest
low power data link technology in your hands. For
surveyors that need to make the most of every day,
the Trimble TDL 450 series is a giant step forward in
radio technology

Field Configurable and Built to Last
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 lowerpower
output extends 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.

Performance features:

  • High Over-the-Air Link Rate:
    • 19,200 bps (both GMSK and 4FSK)
    • Supports 1 Hz RTK corrections for multiconstellation
      receivers
  • Configurable Transmit Power:
    • Trimble TDL 450H power settings:
      4 user-defined power levels from 2 W to 35 W
    • Configurable from the front panel up to the
      maximum power output setting for your region
  • Available Bandwidth:
    • 410 MHz to 430 MHz and 430 MHz to
      470 MHz models
    • Designed for high performance over the
      entire band
  • Software-controlled Channel Bandwidth:
    • Software configurable for both 12.5 kHz and
      25 kHz radios

Versatility, for Continuous
Productivity

Easy-to-use and highly reliable, the Trimble TDL
450 series radio is capable of broadcasting,
repeating and receiving real-time data used by
Trimble GPS/GNSS receivers. Its compact size
allows it to be easily mounted on the same
tripod as the receiver or on its own tripod
using mounting hardware included as standard
equipment.

As a transmitter, the Trimble TDL 450 series
seamlessly broadcasts corrections to radios and
radio-enabled devices. Network coverage can be
enhanced by the use of one or two repeaters.

As a repeater, the TDL 450 series enables you to
reach inaccessible or obstructed locations due to
its extended range and seamless coverage around
obstacles. Because it is so versatile, one extra
radio can be used as a backup or as a “spare” for
multiple tasks.
