when I posted the message I got the BS about the server being busy, so maybe it didnt take the message
here is the condensed version
as bill said, I just bought the $10 UHF antenna and plugged it in and instantly got every over the air HD channel (including CBS)
but my friend one upped me and he just plugged his regular cable into the antenna input, so now he can change his TV input to "air" or "antenna" and he gets CBS HD by using charter's cable as the antenna
so as long as your TV has a built in HD tuner, you're good to go for March Madness and the masters
