The Hdtv Antenna: Some Considerations Of Owning

By:


Perhaps High Definition Television (HDTV) will have been the legacy of satellite positioning, and those people who are unable to get satellite TV can enjoy an HDTV Antenna. They are designed for both indoor and outdoor use by applying digital TV reception, which is free, and represents a new way of watching television while being easy to install.

Gone are the days of hoping to get a good picture instead of a snowy screen or ghost images, or both. That is not the case with HDTV antennas where you either get a good picture or absolutely no picture at all. Most daytime and local broadcasts are not in high definition, yet. This means Primetime is about the only programming that currently uses this technology.

Considering that most of the selections for digital TV broadcasts are in large metropolitan areas, more than 99% of the homes in America have access to local stations that broadcast in digital. 89% of those are able to get upward of 5 channels of free television viewing.

Although they provide a choice of nearly one thousand channels, satellite and cable companies do not have the best delivery because they use data compression which causes the picture to distort. Resulting in ghost effects and soft images, sometimes both. However, off-air HDTV antenna reception is so superior in quality it is the best for watching programs, and it is free.

Indoor antennas are relatively small so they will sit on or near your TV. Outdoor antenna are much larger and intended to be mounted on the roof or attic. Usually, the larger the antenna surface the stronger the signal it will provide. The relative strength of the signal is referred to as "gain" and measured in decibels (dB). The higher the dB the greater the gain.

The same kind of frequencies that were used in the past are used for digital broadcasting. And VHF low band is channels 2-6, with high band being channels 7-13, and UHF is channels 14-51. Some of these got switched around when the digital transmission technology was introduced.

Signal amplification is always a good thing, because the stronger the signal, the better the picture. Antenna amplifiers can be inside the antenna box, and you can get one that is external. The internal amplifier might be best since it has very little distance for extra interference to become a problem. Outdoor amplifiers are sometimes called pre-amps, and pose a situation of gathering additional signals, as well as noise.

As with any type of antenna, during the installation process it will have to be positioned to get the best results. It might even help if someone else is there to keep track of the TV and report when the picture is coming in clear. However, most of the newer televisions have onscreen navigation menus that provide for adjusting signal strength. If you are planning to install HDTV Antenna, you just might be glad you did because it is also free.
