I recently installed an RCA ANT751 ($35 shipped) in an attic by a dormer window. It was inexpensive and does a fairly good job pulling from two tower clusters from the north (including ch 44 and it's 34 miles away) and a nearby PBS on the backend. No amp installed. There haven't been any breakups seen either.

I like the the 751; it is pretty small and easy to install and it'll get UHF & VHF.
