You can connect your HDHomeRun with Plex too. It’s really a nice setup. Plex can work like a DVR to record live channels and even has some capability to remove commercials. I’ve started letting NFL games be DVR’d and commercials stripped before watching the game. It’s a much better experience if you can tolerate the delay.
I just got an HDHomeRun that I use with an antenna and love it. I use Mac and they are one of the only boxes that works on Mac.
They don’t have a native Linux client, but you can use VLC supposedly: https://info.hdhomerun.com/info/linux
