My parents live in a bad signal area and have asked me to install a loft-mounted aerial for their hi-fi system. I have done this many times for TVs, but radio is completely new to me. Please forgive my ignorance here! Here is an extract from their hi-fi manual which shows that AM, FM and DAB are all separate inputs. From researching online, I understand that AM, FM and DAB aerials are different, so I am happy to install three separate aerials in the loft if necessary. Is this the best way? If so, what wallplate would I need behind the hi-fi please?
