Hello, i've recently switched to freeview from freesat for our main tv because i got a good deal on a fox t2 recorder. Now the problem is the signal strength is between 60 - 70%, quality is at 100%. Nonw the reason i'm questioning it is because our tv upstairs in the bedroom with built in freeview has 100% for signal and quality, i think it does have a better picture because on the fox picture i can see some ghosting around the edges. Why would i be getting to different signals strengths? Also our aerial is in the attic and not on the roof.
