I don't have an antenna to test with.
I own a Zenith silver sensor, but lent it to a friend. I guess I should try to get that back.

I was actually expecting to get basic cable over my cable modem line, but Time Warner figured out a bastardly way to not make that happen. Some people mentioned that with basic cable, they were getting HD locals in the clear, tunable with an OTA receiver. Time Warner wants $23 a month for 30 channels and no discount in my cable modem bill. No thanks. So, it seems I will have to wait for my new access card to arrive to experience some HD goodness.
