If you are experiencing break up of channels especially if you have a tv aerial that isn’t that old it maybe 4g interference.
4g interfence is caused by the close proximity of the Digital TV aerial frequencies and mobile phone masts.
If you live near a mobile phone mast that is transmitting on similar frequencies this could be your problem usually notice the breakup and the busy times of the day early and tea time onwards.
