Our UHF signal here is pretty bleak, Prime is watchable but fuzzy, and I was surprised that my new Samsung TV was not only able to actually pick up Freeview, but give me quite a stable picture, even on TV3 with the 1080i/AC3 broadcast.

But it dropped out a fair bit, checking the signal strength it was hovering around 60%-65% with 2 "bit-errors" whatever that equates to. We had an in-line VHF/UHF signal amplifier laying around, I plugged the power half of it in near the TV, and put the amplifier block onto the coax in the garage up near the antenna, turned it all on and the signal strength went up to being around 85-90% with no bit-errors. I'm not entirely sure where we got this thing from but they don't appear to cost much, all it is, is one of these things:

and the associated power supply for it. DSE have a part # L4697 which looks like the same idea, but I'm not sure if it comes with the power supply or not.

It worked out a lot cheaper than getting a new UHF antenna anyway, might be handy for other people too.
