My tv is going on 20 yrs old. I just want to access what is available over the airwaves. And preferably on 2 tv's
Well you're about a year too late making this move as the goverment was actually giving out coupons for the free purchase of these digital coverters. Now you'll have to buy one. Ebay might be a good place to find a cheap one from someone who has upgraded their TV to digital. I'm sure there are others who have more information on these digital converters, hopefully they'll have more to offer than I do. I myself don't have access to digital channels via antenna as you need to be fairly close, not the 75+ miles in the mountains that I am. With an analog antenna, I could get a weak channel full of snow but you could still get it. Hell I could get a Boston channel back in the day from 350 miles away to watch the Boston Celtics from vermont, even tho I had to sit 20 feet away to make out the picture.

With a digital channel, you either have a strong enough signal using an antenna for a picture or you don't, there's no middle ground so the distance is critical.
Cheers,
