No analog channels?

I just got my first hdtv today, its a 32" sharp aquos. It has a hdtv tuner in it. Im using it mostly for gaming, but Im frustrated that I cant get ANY over the air HD channels. Im about 25 miles from Chicago where the signals are broadcast from. I know thats not really close but i should get something right?

I went through the programming and it found none! Is this odd? What should I do? Do I need to buy an HD antenna?

EDIT: I mean digital over the air. Also the manual says that I need an HD antenna but I thought I could at least get something from it. Im trying to program it again i'll let u know if i have any luck. Isnt this odd though no over the air signals at all?

Yes there is.

I do have a plug in, powered regular antenna though, got it from radio shack a year ago. Should I try that, would it have the same results??



indeed.

Looks like James was onto something. I hooked up my powered antenna and im getting all the analog channels and a handful of digital ones (3 to 4). Thanks a bunch, but I'm still under the impression there is a thing such as an HD antenna. Is that just marketing stuff you're saying?
