Have a look at this: https://github.com/tgorgdotcom/locast2plex
It is a super simple container to that represents a virtual antenna and tuner to Plex for DVR capabilities.
Locast.org is a non-profit service to stream your local Over-The-Air TV Channels. Locast is funded through donations; and does not provide DVR capabilities. This project offers the streams to Plex so that PlexPass users can create a TV Tuner and use Plex’s DVR capabilities.
