Product Description
The Stonex SR35 is a high-power radio modem designed to extend RTK correction coverage for GNSS base and rover setups. With selectable transmission power from 5 W to 35 W, it reaches distances of up to 50 km. Multiple operating modes transmitter, receiver, repeater, and network repeater make it adaptable for a wide range of surveying and monitoring applications. The network repeater function bridges GSM and UHF by receiving RTK corrections through the integrated 4G modem and retransmitting them via radio.
The SR35 supports up to 200 programmable channels and is compatible with leading protocols (Trimtalk, Trimmark3, Satel, Transparent EOT). Configuration is simple through PC software or the dedicated Android app, while Bluetooth ensures quick connectivity. Its rugged IP67-rated housing protects against dust, water, and extreme temperatures.
