Installation and Selection of an Antenna for HDTV

TV antennas like relics from the last century, but a growing number of viewers to find, they are indispensable, always in the best picture from their HDTV’s.

Over-the-air HDTV signals are the best you can
The conversion to digital television has the most annoying picture distortions - snow and ghost images - the analog off-air reception so hit-or-miss. With digital TV signals (standard definition and high definition), you are either a sharp, ghost-free picture or no picture. As most local and syndicated programming is not high definition, it is typical for the local channels to broadcast their digital signals into standard-definition during the day, and then switch to the widescreen HDTV during primetime.
Even if you have never been an off-air antenna in front, there are several good reasons to consider, one to your other TV signal sources:

Local digital TV broadcasts are everywhere: Even if the largest selection of digital TV transmissions are in large cities TV markets, more than 99% of U.S. TV households have access to at least one local digital station, 89% can five or more stations. You can find out which stations in your area, the digital broadcasts by visiting the website listed Antenna web.
Over-the-air digital reception provides the best image quality: cable and satellite providers offer tons of channels, but to do this they are data or other techniques to compromise, that the image quality, leading to a "soft" image, disturbing video "artifacts" (distortion), or both. Off-air antenna reception is the best way to enjoy HDTV programs at full resolution the TV networks.
Access to all your local channels: Bandwidth limitations also mean that cable and satellite providers can not all local stations in your area, or not, they in High Definition. Also contract disagreements between local cable operators and local broadcasters can mean that major networks may not have cable TV in your area.
Access to out-of-channels of the city: With the right equipment and reception conditions, which some viewers may even be able to get out of town channels, some of which are the sports programs, the local blackout.
Over-the-air signals are free: In addition to the cost of the acquisition and installation of an antenna, receiving over-the-air HDTV is free.
Of course, in addition to an antenna, you need some kind of HDTV tuner to receive digital TV programs. If you have an "integrated" HDTV, the tuner is already in the TV. If you have an HDTV-ready TV, you must connect to a separate HDTV tuner. If you currently have the HDTV package from satellite providers DIRECTV ® or DISH ®, your HD satellite receiver, probably an over-the-air HD tuner.
