Thought I had the same problem but Fox is ok here. I did some research and found a site called tvfool.com that had a lot of reception and antenna information.
Yep, to anyone wondering, use tvfool.com or antennaweb.org to find your channels and what frequency they're on. Most UHF antennas don't work for VHF and vice versa... Unless your signal is strong enough, in which case a paper clip will work.
And no offense to xwalker or anyone else, but Terk is pretty much a terrible brand... Their products are ok in some cases but are horribly overpriced. For something local, look at the Winegard Freevision from Home Depot
http://www.homedepot.com/p/Winegard-Freevision-Outdoor-HDTV-Antenna-FVHD30H/203972856 or one of the Radioshack Antennacraft models
http://www.radioshack.com/product/index.jsp?productId=3766859. If you live in a big city near a Fry's, they carry Channel Master products that are good. These are "real" engineered antennas... In most cases you don't want anything with a built-in amplifier, as those usually add as much noise as anything.
If you want to order something, a company called Solidsignal.com is very good.
And if you're handy and enjoy that kind of thing, you can make an excellent quality antenna pretty easily with hardware store parts for just a few dollars. Google Gray-Hoverman antenna. These aren't the humongous ugly old TV antennas you used to see (nor are the ones posted above), but smaller ones you can use inside if you want to.
Main point is that if you've tried something from a big box store and it hasn't worked, don't give up because those antennas usually aren't any good and the ones posted above (or even better ones) have much stronger gain and don't cost much, or any, more.
Just some tips from an early HDTV adopter who went through all this years ago when OTA was the only option for HD.
All that said... I'd bet this is all resolved before tomorrow. DTV doesn't want all the bad pub from people who don't know about OTA missing their NFL games.
