The Basics of High Definition TV Antenna
The increase in the sales of high definition televisions is proof of the consumers' interest in HDTVs. While enjoying the new features of their HDTVs, they are also taking advantage of the numerous channels their HDTVs can access with the use of a high definition tv antenna.
Digital programming is being considered by a lot of consumers today because of a mandate issued by the Federal Commissions Commission that says all analog signals will be shut down by February 2009. In order for consumers to receive digital broadcasts, they have to buy an ATSC digital tuner or set-top box for their analogs. With digital programming, viewers can have excellent picture quality, quality audio and surround sound, and get more programming via sub-carrier channels.
Free digital and high definition signals can be received if: you reside in a place that can receive OTA broadcast signals; the broadcast stations in your area transmit a digital signal; and your HDTV is equipped with a digital (ATSC) tuner or if you have an HD-ready TV with an external HD receiver.
The function of a high definition tv antenna is basically the same as that of an analog antenna. Both pick up over-the-air (OTA) signals transmitted in standard or high definition. There are a lot of television antennas available in the market today. They differ in size, quality and price. But before purchasing a high definition tv antenna, consumers should take some things into consideration.
The kind of high definition tv antenna is not the same for every household. Choosing a high definition tv antenna should not be based only on the distance from the broadcasting station. To get a good reception, the signal conditions should be precisely distinguished and from there, a high definition tv antenna that works best under the perceived condition should then be selected. Consumers who have cable or satellite services may not need a high definition tv antenna.
Converting to HD can be costly for some consumers. A new HDTV can cost consumers from several hundred to thousands of dollars, while a high definition tv antenna can cost around $20 to $100 for most models. Most other accessories related to high definition technology can also be pricey.
Upgrading to a high definition format may be an expensive move. But the fact that the country will phase out analogs in 2009 and go digital from then on, consumers can save in programming costs over the years.
