Hey wado66:
Almost all TVs you can buy today will have a channel guide for OTA. After you hook up your coax cable to the TV and run a channel scan according to specified instructions, you will see a guide of what you have in your area, etc.
Unless you have an older TV (pre 2006), in which you would need a digital converter, you should be good to go with your current model.
Enjoy your free TV viewing and best to you!
