The poster is correct. There is a law, I cannot remember where it is stated and where I read it, but I have heard it and I did check when I only had cable. I got all the broadcast stations in HD no less without a cable subscription using my QAM tuner on my TV and on my HD Homerun.

Quality usually will not be nearly as good as receiving over the air though. At least that is my experience. Most cable operators will compress their stations, some more than others. It is obvious if you have seen or are used to viewing with rabbit ears.

My experience is the opposite. Before I knew about the above, I bought a digital antenna from Home Depot. I got barely any signal.

Now, I get HDTV quality on a few networks.
