> For OTA HD reception you would have to buy an OTA HD STB plus antenna - probably cost you $200-300. Hardly free! Even paying the cable company $6/month for HD box rental it would take 3-4 years to equal the upfront cost you would have to pay for OTA HD equipment.
This makes the probably incorrect assumption that this guy is currently a cable subscriber -- since cable penetration in Dallas-Fort Worth is below 50%, that is a bad assumption. Add in the cost of a cable "lifeline" subscription plus the HD box rental, and the cost of cable is such that he'd be better off with the OTA tuner -- it would pay for itself in under a year!
Now for some useful information:
1. HDTV broadcasts are available over the air in Dallas for ABC, CBS, NBC, Fox, UPN, WB, and PBS -- and all these stations broadcast at high power and are easy to receive.
2. You'll need an HDTV tuner to connect to your 17" LCD monitor. Wal Mart sells a box that will do this at many of their stores for $199. If you don't want to go to Wal Mart, you can keep an eye open at Best Buy, Circuit City, etc for an "open box" deal on a HDTV tuner...or you can pay a bit more for something new. You might also check online to see what is available. For more on recommended tuners, check out the HDTV hardware thread here.
3. Finally, you'll need an antenna. Any antenna that provides a reasonably ghost-free picture on both high-band VHF (channels 7 through 13) and UHF (channels 14 and up) should do a good job of bringing in the digital HDTV signals here locally. Since I don't know where you are in the area, I don't know how much of an antenna that would take -- in my location (Plano) an indoor antenna can do it.
In any event, once you do get the tuner, you will be blown away by how good a television picture can look. HD broadcasts of shows like "Smallville", "Lost", "Enterprise" and most other prime time shows look incredible!
