Telemetry Radio Base Station – Variable Frequency (RLRTMVARBS)

A long-distance, variable-frequency radio that can transmit data between 403 and 470 MHz.

The variable frequency and power of these radios make them viable in many countries. Please check local RF licensing regulations.

With a typical max range of 10 km (at 1 W), the radios can be used with a Base Station to provide DGPS radio coverage to most areas of a proving ground.
