I have no cable just a plug in Antenna , with my new Roku tv I’m unable to watch wgn news live in the morning. It only gives me live Roku channels. Can I switch off to watch my previous 4 channels with my Antenna?
Somewhere in your settings there should be an option to "scan for channels" if it didnt pop up when you connected the antenna.
Adding to @BronzeCheetah response, in order to scan for your antenna/Over-the-Air/OTA channels, navigate to Settings/TV Inputs/Live TV/Scan for Antenna Channels
If you want to seperate your antenna/OTA channels from the Roku Streaming Channels Live TV, after you have successfully scaaned for your antenna channels, navigate to Settings/TV Inputs/Live TV/Manage Channels/Hide Streaming Channels.
In order to access the Roku Streaming Channels Live TV if you choose to hide them, you can either go to Live TV in the Roku Channel channel/app, or by selecting Live TV from the Menu items on the left side of Home Screen.
