TCL 50" 4K UHD Roku Smart LED TV

Does this thing have its own broadcast TV tuner? It appears not to. At least I cannot find anything about it so I assume if I want to watch over-the-air broadcast TV I need to have a digital tuner too. Is that correct?

It uses the Roku product as it’s tuner.

There are manuals here for download. I found a section on setting up the tuner. It’s under the antenna section but applies to direct connection of cable as well.

I have a 40" TCL and use the Time Warner Cable Roku app to view TV, On Demand, etc.

Thank you.

It appears to have a tuner built in. (aside from the Roku) for OTA.
