Harxon HX-DU1603D-SE External UHF Rover Radio Kit for Trimble R8s

Harxon HX-DU1603D-SE External UHF Rover Radio Kit for Trimble R8s Turn your Trimble R8s into a UHF-capable rover with a complete external radio package designed for receiving local RTK corrections from compatible construction and surveying base stations. Built around the Harxon HX-DU1603D-SE, this package provides a practical solution for Trimble R8s users who don't have an internal UHF radio and want the flexibility to work with different UHF base stations in the field. The HX-DU1603D-SE operates across 410–470 MHz and supports commonly used surveying radio protocols including TrimTalk450S, TrimMark3 and SATEL, making it well suited to working around Trimble and other compatible UHF infrastructure. What's included Harxon HX-DU1603D-SE external UHF radio Harxon UHF whip antenna Trimble R8s external radio interface/data cable External 12 V field battery Battery charger Required power connection lead Package configured for use as an external rover radio Designed for flexible site work Rather than being locked to one particular base station, the HX-DU1603D-SE can be configured to match the UHF settings used on different sites. The radio supports: 410–470 MHz UHF operation TrimTalk450S TrimMark3 SATEL 12.5 kHz and 25 kHz channel spacing Adjustable frequency/channel settings Adjustable air-link settings RS-232 communication with the GNSS receiver This makes the package particularly useful for contractors and surveyors moving between construction sites where different compatible UHF base stations may be in use. Trimble R8s connection The package is designed to connect the external Harxon radio to the 7-pin Port 1 connection on the Trimble R8s, with the external battery supplying power to the radio. The HX-DU1603D-SE accepts a wide 9–36 V DC input range, making it well suited to a portable field battery setup. Before ordering UHF frequencies and radio settings vary between sites. The rover radio must be configured to match the frequency, protocol, channel spacing and applicable settings of the base station transmitting corrections. Trimble R8s receiver is not included.
