Just downloaded and trying to get to grips with PLEX.
One of my requirements is to be able to dad number go UK terrestrial channels (I do not have an antenna).
My research suggested it was possible but now having got going it is clear that all of the help articles predate plugins being removed. I have searched the forums (I think) without anything coming up. How is it done now?
There are HDHomerun emulators but then you fall outside the Plex supported framework. Plus you have to be somewhat computer knowledgeable to do the setup and configuration not to mention finding a legit IPTV provider.
Have you looked at the Live TV section to see if there are channels there that would suffice? Hopefully in the near future Plex will add some integration with IPTV providers.
