Welcome to the Roku Community, shorelinemike!
Thanks for letting us know about this. We'd be happy to help you find and stream your OTA Live TV channels again.
If setting up your TV input under Settings > TV inputs > Live TV shows the option rescan instead of set up input, this means that you've already set up your antenna and are ready to go.
If this is the case, please try finding the Live TV Guide icon on your Home screen with a white background instead of the purple icon of Live TV on The Roku Channel to see if this makes any difference.
Let us know how it goes, and we'll go from there.
Best regards,
Carly
