Can someone tell me what I need to do to connect 4 TV's to one external aerial to receive Freeview on all the TV's. I currently have an old aerial up on the roof that inputs into one Sky+HD box downstairs that is connected to a HDTV. Judging by the age of the aerial (20+ years old) I would think that this needs to be replaced to receive Freeview on this TV (and then get shot of Sky+HD). I have bought another HDTV that is in my son's games room and I also have 2 portables that I want to connect up to the same aerial to receive Freeview on all of the 4 TV's. All of the TV's have Freeview built in. Can someone explain what I need to purchase and how I need to connect them up as I don't think 4 antenna's is the way to go..... Many thanks.
