Our samsung smart tv makes it very confusing to watch over the air antenna TV.
First off to get it to connect to / recognize the antenna was connected I had to go to
Settings > General > Start Setup
After that the tv realized the antenna was connected and scanned the channels.
But after this the Guide still only showed the “My TV+“ channels and not the antenna channels.
To fix it do this
- press home button and menu comes up
- go to tv+ icon
- in the menu above that go to Channel List
- on the remote press the right arrow button
- in this right menu pick Air
After that the guide should show the OTA antenna channels.
