I tried to use the DTV antena box but not many channels came in. The NBC channel was very unpredictable on the reception. I’d love to be cableless but the reception with the DTV box just wasn’t good enough. Of course nowadays one can go without tv at all for sports. You can see all baseball, football, basketball and hockey games LIVE over the internet. I’ve had some times when I did not have cable and just used the antenna (before the DTV thing) and it was OK althought the reception was of course inconsistent. You definately do alot more reading when you dont have cable plus it was really nice not to have to write that check for 50 or 60 bucks to the cable company.
I don’t know if you’ve tried it already, but if you go to the dtv.gov website, you can get more details regarding reception of digital signals.
It also has a ‘reception maps’ link which will show you the signal strength of nearby channels specific to your location and recommend the best type of antenna to purchase.
There are wireless blue ray dvd players that will send your computer signal to your TV. Check out nexflix and HULU ... between those options and an antenna you might be pleasantly surprised.
Are you using an indoor or outdoor antenna? If outdoor how high is it? If indoor, have you tried placing it near a Window? Are you on the side of the house most of the antennas in your area are located?
