Welcome to the Roku Community, Merfreet!
We're grateful that you've reached out for support. We'd like to provide further information about this.
In addition to what our Community Guru provided above post, depending on where you live, you may be able to receive free "over-the-air" TV broadcasts from nearby TV stations using an HDTV antenna. 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. You can visit Antenna Web to learn more about HDTV antennas and how to access "over-the-air" TV in your area.
Here's our support article dedicated to this: How to set up and watch live TV on your Roku TV system
We hope this helps!
Best regards,
Carly
