Over-the-air HDTV signals are the best you can get
Sens specializes in home theater and installing digital tv antennas. The switch to digital TV broadcasting has eliminated the most annoying picture distortions — snow and ghosting — that made analog off-air reception so hit-or-miss. With digital TV signals (both standard-definition and high-definition), you'll either see a crisp, ghost-free picture or no picture at all. Because most local and syndicated programming is not high-definition, it's typical for local stations to broadcast their digital signals in standard-definition during the day, then switch to full widescreen HDTV during primetime. Even if you've never used an off-air antenna before, there are several good reasons to consider adding one to your other TV signal sources:
Local digital TV broadcasts are everywhere: Although the widest selection of digital TV broadcasts are found in large metropolitan TV markets, over 99% of U.S. TV households have access to at least one local digital station; 89% can get five or more stations. You can learn which stations in your area are providing digital broadcasts by visiting the Antennaweb site.
Over-the-air digital reception provides the best picture quality: Cable and satellite providers offer tons of channels, but to do this they use data compression or other techniques that compromise picture quality, resulting in a "soft" image, distracting video "artifacts" (distortion), or both. Off-air antenna reception is the best way to enjoy HDTV programs at the full resolution the TV networks intended.
Access to all your local channels: Bandwidth limitations also mean that cable and satellite providers may not carry all the local channels in your area, or may not offer them in high definition. Also, contract disagreements between local cable operators and local broadcasters can mean that major networks may not be available via cable TV in your area.
Access to out-of-town channels: With the right equipment and reception conditions, some viewers may even be able to receive out-of-town channels, some of which may carry sports programs that are locally blacked out.
Over-the-air signals are free: Aside from the costs to purchase and install an antenna, receiving over-the-air HDTV is free.
Of course, in addition to an antenna you'll need some type of HDTV tuner to receive digital TV programs. If you own an "integrated" HDTV, the tuner is already built into the TV. If you have an HDTV-ready TV, you'll need to connect it to a separate HDTV tuner. If you're currently subscribed to the HDTV package from satellite providers DIRECTV® or DISH®, your HD satellite receiver probably includes an over-the-air HD tuner.
