If you already have the HDTV antenna connected to the Live TV input of your Roku TV, feel free to follow the steps below:
- Go to Home.
- Select Live TV.
- If Live TV is missing, you can add it by going to Settings > TV inputs > Live TV > Set up input.
- Follow the instructions on the TV screen to complete the setup.
Note: The placement of the HDTV antenna can affect which TV stations you may be able to receive and the quality of the TV signal. It is normal for the initial channel scan to take a while.
For more information, check out this Support article: How do I set up the Live TV input on my Roku TV™?
I hope this helps!
