This is a flexible whip-style UHF antenna tuned to the 450-470MHz band commonly used for RTK radio datalinks, with roughly 4dBi of gain and a threaded TNC connector for direct mounting on a receiver or radio housing. It is a lightweight accessory antenna meant to extend and stabilise UHF radio range between a GNSS base and rover during conventional radio RTK surveying. Its compact, low-profile design makes it easy to pack alongside a receiver kit without adding much bulk.
