There are a couple of internet sites where you can put in your address of zip code and see the channels that are predicted to be able to be picked up with a 50, 60, 100 mile antennae. One is:
Antennas Direct | TV Transmitter Locator and Mapping Tool
I happened to bring a 60 mile radius antennae with me from NJ and the channels were not worth it to me. I live near Spanish Springs. If you are happy with just a few channels in combination with a service like Netflix or Hulu....it would be very inexpensive. Direct TV is expensive, but I wanted the channels....so I pay.
