Plex's new live TV beta will be available for all users with a Plex Pass. As long as you have an antenna and a digital tuner, you can stream HD digital broadcast channels, including local news and sports, from directly within the Plex app. Any digital antenna will work with Plex, and the company is continuously working to add more tuner support... Plex Pass users don't pay extra for live TV streaming—it's bundled into the subscription just like other features, like DVR and cloud syncing...
The service is another cord-cutting way to watch live TV, but Plex's TV streaming is quite different from that of YouTube TV or Hulu with Live TV.

If you have an antenna and a tuner installed, you can watch live TV on Plex from any of the networks that broadcast free OTA content.
