I want to use an OTA HD antenna...


but I don't know what brand to buy. Also, my CRT doesn't have a tuner, so I need a recommendation on that too.

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.).
You can go here TV Fool to see what channels are available in your area . It will give you height and the direction calculations in which your antenna needs to be pointed.

I would try Radio Shack for an HD antenna. The basic one is no more than $30 and it will give you great reception. You can always add an amplifier if needed. If you live in a metropolitan area..chances are an amplifier isn't necessary.

From comparing cable HD verses over the air HD..over the air wins hands down! Not sure why, my best guess is because of the compression used by the cable companies. The over the air channels are uncompressed and it doesn't need miles of copper and line amplifiers to reach your home.

You may want to grab your two free $40 coupons for the digital tuner or tuners. $80 saved.. is $80 saved, no matter how you slice it.
