FAQ number one.
Q: What kind of antenna should I get?
A: A little indoor antenna on top of your TV might be all you need! And if that doesn't work then a larger antenna in your attic will probably do the trick. Don't get all spun up about a roof mount just yet. You need an antenna that can do UHF and VHF. Atlanta sources for antennas include Fry's (in Duluth and Alpharetta) and Dow Electronics (in Duluth); popular attic/roof models include the Antennas Direct DB2 and Channel Master 4228.

I have a friend who lives in Sugar Hill (35 miles out) and was able to pull in 30 services with just set-top rabbit ears, although I think that's an extreme case and really just good luck.
