HDTV antennas have become important elements in our life today, as many countries now broadcast television exclusively in high definition. The antennas allow us to easily watch high-quality television programs. Before purchasing an antenna, you are reminded to make your selection carefully. You cannot just get an antenna as it may not suit your digital TV due to some factors. Having some knowledge about antennas is essential.

To save your valuable time searching for antenna related information, I have summarized some important facts here. You can take the following points as a reference.

• First things first, let me ask you a question. Why do we need HDTV antennas? What is the difference between standard definition and high definition? For your information, HDTV antennas transmit more than 1000 lines of color. However, for standard definition, only 480 lines of color are transmitted. In other words, the more lines of color that are transmitted, the sharper the image quality can be. Now, you must know why so many people are talking crazy about HDTV and its antenna. If you want to watch a free broadcast, you sure need the antenna to get a clearer view. However, if you are the cable or satellite subscriber, you do not need to fix an antenna. You can watch HD programs automatically.

• There are many types of antennas on the market. They have different characteristics and functions. They come in different sizes. Some small antennae look like rabbit ears. You can also find large ceiling models. The size of an antenna affects the picture quality of television programs. The larger the antenna, the clearer the reception.

• In addition to the size of the antenna, its position also plays an important role. If you want a clearer view, you should place your antenna in a position where there is no obstruction. You are reminded to avoid fixing your antenna where there is a tall building in front. If it cannot be avoided, the image quality will be less satisfactory.

• HDTV signals are output at the same frequencies as analog signals. If you already have a standard antenna with you, you don’t need to spend more money to get a new HDTV antenna. You need to get a converter box to pick up HDTV signals. However, if your standard antenna is too old-fashioned, you may not be able to watch HD programs. If this is the case, you need to find an HDTV antenna to solve the problem.

• Not all digital televisions can be combined with HDTV antennas. These antennas pick up the broadcast with a wide 16: 9 aspect ratio. If you are watching the programs with black bars at the top and bottom of the picture, it shows that your TV is not wide screen. You should check e-shops for technical recommendations.

As a smart consumer, by knowing the facts about HDTV antennas, you will be able to make smart decisions.
