Really sorry but just wondered if anyone could please? When myself and ex bought the house it was new so did not have an external aerial. He left a long while ago so now I am trying to "sort things out" and learn to understand things (well try). My son cannot get a tv signal despite internal areas being plugged in. They just don't appear strong enough. I have been paying for him to have his own sky box in the room however I can't afford this any longer. How can I get a signal to his tv (with inbuilt freeview) or do I need a Now TV box? How do they work? Sorry for so many questions I am really embarrassingly stupid (obviously). 
Thank you
