Key Features

Wide Frequency Coverage and Flexible Channel Bandwidth

Covering the 410–470 MHz frequency range, the radio features an advanced data link design for consistent communication performance across the entire 60 MHz band. Software-configurable channel bandwidth supports both 12.5 kHz and 25 kHz operation, providing flexibility when matching channel settings with compatible radios in existing GNSS/RTK communication systems.
Multi-function Interface for Convenient Field Operation

Designed for easy mobile use in demanding field conditions, the radio features a multi-function user interface that simplifies operation and configuration. Convenient access to radio settings helps users prepare equipment for deployment and adjust operating parameters as field requirements change, supporting efficient workflows for surveying and other outdoor positioning applications.
Configurable Transmit Power for Different Operating Needs

Selectable transmit power levels of 5W, 10W, 15W, 20W, 30W, and 35W allow users to adapt the radio to different communication requirements. This flexibility helps balance transmission needs and power consumption, enabling users to select an appropriate output level based on site conditions, deployment distance, and available power.
Repeater Function for Flexible Communication Coverage

The radio supports repeater operation on the same frequency or on different frequencies, offering flexible options for relaying data between field devices. When deployed as part of a suitable radio network, the repeater function can help extend correction data coverage and reach areas where a direct radio link is limited by distance or terrain.
