I'm a little confused and I was hoping someone could straighten me out. I have a 50" Sony HDTV as well as an ATI TV Wonder 650. The 650 says it can record Over-the-Air HD channels with the use of an external antenna. On my TV, however, I have no external antenna, only the cable coming out of the wall into the cable box, and I receive the over the air HD channels just fine (note that my digital cable package does not include the HD channels). Why am I able to receive the over the air HD channels on my TV without an antenna, while the tuner card says it needs one? Do I really need to go get an external antenna for my card? If so, any suggestions for which antenna I should buy?
Note: I also live within 10 miles of the broadcast towers. Can someone help me out?
