Hello,
The frequency ranges supported by the Pointing antenna does cover frequencies required for the complete coverage of the operating bands of the RUTX50, including 5G. The thing to keep in mind is that RUTX50 utilizes MIMO technologies, for which, unlike with other Teltonika routers, all of the antennas are equally important to provide the best performance and fastest speeds.
Nevertheless, you can use this antenna with the aforementioned router.
Best regards,
