Re: Freeview with no aerial?..
I'm not against loft aerials, but they come with their own pitfalls (metal water tanks and lead work). If you decide to DIY a loft aerial install, I would go for a High gain Group B aerial. Group E aerials are harder to get hold of and can be more expensive. You would probably lose the Mux D channels until June when Black Hill goes fully digital, and then all channels will fall neatly into Group B. Try without a pre-amp first. You can always install one afterword if you need to.
