Hi @IanLogan,
Thank you for letting us know about this issue, and welcome to the Roku Community!
We will be more than happy to take a closer look into this issue that you're having with the live TV channels since it is not being detected. What device are you using right now? (e.g., Roku Express, Roku Streambar, Roku TV—specify TV) If this is a Roku TV, does the back of your Roku TV have a connection for an antenna?
With detailed information, we will be able to assist you further.
Thanks,
John
