I live in Wichita, Kansas and just curious if local channels are available, such as KSCW, KSNW, KWCH and KAKE?
Roku TV or separate Roku device connected to a TV?
Roku TVs have antenna inputs which can connect you to over-the-air local channel broadcasts.
Roku devices have no antenna inputs and so can only receive local channels via installed channel apps that include local channels, like Hulu plus Live, YouTubeTV, fubu, and a number of others. Note that some TV stations do have their own Roku apps that allow you stream local content like local news (usually not network or syndicated shows).
