If I get a twin tuner freesat pvr will I need to have two aerials put in? I have just realised I can get freesat via a aerial socket in my new build flat that says "sat" on it. If I was to hook a pvr up to that would it just connect to one tuner? How expensive/difficult is it to get another one put in (bearing in mind I live in a block of flats). Any help would be great, I am trying to work out if this or a freeview hd pvr would be my best bet.
