Does anyone use (just) an antenna for their TV reception?

We haven’t had TV for years and we bought a nice plasma TV early this year for DVD’s and for streaming Netflix. I have been reading lately how a lot of people are getting rid of Cable in favor of local programing with an antenna. I am wondering if anyone has been successful with this. We bought an indoor/outdoor antenna at Costco and it gives us just a few odd channels but no ABC, NBC, CBS, Fox etc. Are there antenna people who you can call or have come out and look?
