I want to use an OTA HD antenna...

A friend educated me to the fact that our local cable providers carry broadcast HD signals on their cable lines, and one can simply connect the cable line to the ANT IN connector on a tuner to get the broadcast HD signals (but obviously not the cable HD signals). Apparently, the cable companies are required by law to carry the broadcast signals, but they don't advertise this for obvious marketing reasons.

So, if you have cable, then you don't require an antenna, but you still need the digital HD tuner.

Check out the review of the Sony XDR-F1HD tuner at theaudiocritic.com. Super HD tuner at $100.

Tab, Federal law provides that "TV" will always be free. You don't have to steal it, as some might suggest. Terestrial reception is very location dependent however. What is your zip?

My point was that if one has cable already installed (and being paid for), then HD broadcast signals can be used from the cable coax (by using a splitter) rather than installing a separate HD antenna. It's free. It's mandated by Fedaral law. It's not stealing provided one is paying for cable service that provides the coax line to the home.

Now, the OP did not specify if he has cable. If not, then this option is moot, but it's helpful for those who do have cable service and only want/need broadcast HD versus a more extensive cable HD package (for ESPN, HBO, etc.).
