They have analog and digital antennas in store and online.
I had to go to Fry's for an outdoor antenna.
Wait I'm not sure if they have outside home antennas at Best Buy. They have the indoor ones, some which are Amplified. If they do it would be a small one, probably made by RCA. I've seen Walmart carry that one before so that's the only one I would imagine they would have it Best Buy, so don't quote me on that. I know Home Depot two exits north on I-5 has outdoor antennas, and they also have several Signal Boosters and amplifiers if you need to run that inline as well.
They have digital antennas that you can install on your coaxial plug on your tv
