Overview
Reliable equipment. Real-world results.
KS4 is a high-power fixed UHF station for extending correction-data coverage from a permanent GPS or GNSS reference installation. Its SATEL-EASy Pro+ provides up to 35 W of transmitter power and broad over-the-air compatibility for reaching RTK rovers across large sites and difficult terrain.
The current package provides the complete RF path from radio to outdoor antenna: a short 195-series pigtail, broadband surge protector, 30 ft LMR-400 feed line and rugged fiberglass omnidirectional antenna. A YP1150 supply powers the radio from AC service, while a receiver-specific YCSWK interface cable carries correction data from the host equipment.
Fixed radio and antenna installations require appropriate frequency licensing, grounding, lightning protection, weatherproofing and structural mounting. Contact Satel USA to confirm the correct data cable and installation components for the host receiver and site.
