TV broadcasts in high definition provide picture quality at par with or often better than tradition services offered by your satellite or cable provider. Moreover, the transmission of these high-quality channels to your TV is free of cost over the air. TV antennas made for HD reception are available in both outdoor and indoor varieties.
However, the technique for connecting the antenna to an HD television and the way the device receives the transmission feeds are quite similar for both types of antenna.
The UHF transmits high definition signals. The signals have a line of sight from your broadcast tower to the TV antenna. The Earth’s curvature often places a limit on the distance between the broadcast tower and your TV antenna. That is, in most cases, in the range of about sixty to seventy-five miles.
But, many obstacles such as buildings and trees can cause the signals to bounce. This phenomenon referred to as "multipath," often triggers the TV signal to intercept the antenna multiple times, which leads to cancellation.
However, by orienting the TV antenna at a greater height will help you overcome the common obstacles. If installed correctly, an HD antenna will receive all of the television channels broadcast by a local antenna, including many sub-channels.
This feature referred to as "multicasting," allows broadcasters to transmit one HD channel along two or more than two digital channels, often featuring weather, educational and other types of information stations.
Always keep in mind that there is no difference between an HDTV antenna and a conventional TV antenna. Although a lot of people would want you to believe there is some difference between the two, this is only untrue. That is why when you choose an antenna for your HDTV; it is essential to use the same principles or criteria that you apply for selecting a conventional TV antenna.
Some important factors to take into account are the size, quality, range, and cost of the antenna. Moreover, in many cases, it is also vital to ensure your TV antenna has VHF/UHF capability.
Digital TV is often used to refer to TV signals that are sent digitally and allow providers to offer support for multiple channels in the signal bandwidth or output. That is different from an analog signal which can only allow for one TV channel per signal.
However, what differentiates a real high definition signal is its superior digital nature which enables it to offer a substantial difference in both audio and visual quality when compared to conventional digital programming.
As a result, viewers can thoroughly enjoy a high screen and sharp resolution that renders a much crispier and clearer picture as well as a full-screen picture format that provides better action and more vivid colors.
Moreover, a majority of TVs that have Dolby digital sound are often thought to have much better high-definition audio too. A majority of HD TV antennas can connect directly to your HDTV or a decoder box with a particular kind of cable known as the RG-6 coax.
This cable has extensive shielding and enough wire gauge to easily carry and secure weak digital signals from your TV antenna to the decoder.
You do not need a separate HDTV antenna; however, you do need a traditional television antenna. You require television with an excellent digital tuner for the analog TV set to convert the HD or digital signals to analog. Keep in mind your TV antenna is essential to your TV viewing pleasure.
Things were different in the good old days; in case the antenna’s system performance was not at par, you could still watch your TV; however, the picture quality was used to be snowy, but it was possible to watch TV.
On the other hand, HDTV or digital reception is entirely different compared to analog. With HDTV reception you will either receive clear picture or nothing at all. A majority of customers tend to buy the smallest antenna, often wrongly assuming their specifications.
However, when the antenna’s performance is not good, they think that is the best picture quality they can get. If you happen to be one of these customers and carry on this practice and buy television antennas not appropriately designed to receive strong signals, you would be disappointed and frustrated, and have to buy another television antenna.
The bottom line is that HDTV or digital reception is either all or nothing. That is why it is better that you do not scrimp on the TV antenna. TV sets come with built-in digital tuners; however, in other cases, it could be in the form of a set-top tuner.
This tuner can convert the digital signals into analog signals, ensuring your existing analog television would work just fine. A lot of customers assume that they need to buy an HDTV to have a TV that has a built-in tuner; however, this is just not true. The digital televisions available in the market today are merely analog televisions that have a built-in digital tuner.
However, these digital TVs do not have a widescreen similar to HDTVs; moreover, they will cost you considerably less than an HDTV. There is no denying that their picture quality is not as excellent as most HDTVs, but they fare well compared to analog TVs concerning picture quality.
Therefore, if you do not want to spend a hefty amount of money on a brand new HDTV, it is better to buy a regular digital TV.
