Thanks for the suggestions! I checked out a local hardware store and found this antenna
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER which got good reviews, so I thought I'd try it. After pointing it at my local stations (indoors and out) I got 16 channels or so (no Fox/WBFF though).
On a whim I pointed it to the DC stations, and now I get all the local stations (again, except Fox/WBFF) + some DC stations for a total of 28. So that's nice. With some careful adjustment and no passing trucks I get DC's Fox station WTTG, so my end goal of just getting ANY Fox station is mostly accomplished--just in time to watch Gotham next week.
Thanks for the help!
