I'm sure with many of you out there your main TV for you and your families entertainment has a digital tuner. Meaning it has the capability to except a digital signal via a TV antenna. But keep this in mind. Did you know you can run multiple TV's off your ONE (1) rooftop antenna! Knowing this though, just make sure that your other TV's throughout your house are digital also... they're not???! Not a problem. Simply get yourself a digital converter box (you will have to have one for each TV). This device will convert the digital signal your antenna receives to an analog one so your older type TV can display it.
