Do you guys in the US have a type of 'FreeSat' like in the UK? If we are unable to get a digital TV signal via our roof arial, we can get a satelite dish and set-top box to get all the usual channels via Satelite. Might be worth trying before you go making a super antenna!!

Or is the super antenna the whole idea, rather than a tiny little dish!?!!
I lived in Bozeman, Montana for a year, a few years ago, and those pics remind me of there. It was so much fun!! Snow from November till April, yay!!!
