That's what my parents have. They were told that besides the converter box, they had to buy a digital antenna.You may need a better UHF antenna. The old analog was mainly (or maybe exclusively) VHF. That's the downfall, UHF doesn't travel as well, that and you can watch a weak signal on VHF because it's just fuzzier than a strong signal. You can't watch a weak digital signal. My parents are having that problem with some of the local stations. They have a 20 year old DirecTV satellite for the living room, but use an antenna for their bedroom since at the time it was really expensive to get two dishes.
