HDTV antennas have become important items in our life today as many
countries now exclusively broadcast television in high definition. The
antennas enable us to view high quality television programs easily.
Before you purchase an antenna, you are reminded to make your selection
carefully. You can't simply get any antenna as it might not suit your
digital television due to some factors. Having certain knowledge about
antenna is essential.
In order to save your precious time looking
for information related to antenna, I have summarized some important
facts here. You can take the points below as reference.
• First
thing first, let me ask you one question. Why do we need HDTV antennas?
What is the difference between standard definition and high definition?
For your information, the HDTV antennas allow more than 1000 lines of
color to be transmitted. However, for standard definition, only 480
lines of color are transmitted. In other words, the more lines of color
are transmitted, the sharper image quality you can obtain. Now, you
should know why so many people are crazily talking about HDTV and its
antenna. If you want to watch free broadcast, it is for sure that you
need the antenna to get a clearer view. However, if you are the
subscriber to cable or satellite, you are not required to fix an
antenna. You will be able to watch programs in high definition
automatically.
• There are many types of antennas in the market.
They have different features and functions. They come with different
sizes. Some small antennas look like rabbit ears. You can also find
large rooftop models. The size of an antenna affects the image quality
of the television programs. The larger the antenna is, the clearer the
reception.
• Besides the size of the antenna, its position also
plays an important role. If you want to have clearer view, you need to
place your antenna at a position where there is no any obstruction. You
are reminded to avoid fixing your antenna at the place where there is
tall building in front. If it can't be avoided, then you would have less
satisfied image quality.
• HDTV signals are broadcast over 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 are required to get a converter box to pick up the HDTV
signals. However, if your standard antenna is too old-fashioned, you may
not be able to view the programs in high definition. If this is the
case, you need to find a HDTV antenna to solve the issue.
• Not
all digital televisions are able to match with the HDTV antennas. These
antennas pick up broadcast with a wide 16:9 aspect ratio. If you are
watching the programs with black bars on the top and bottom of the
image, it shows that your television does not have widescreen display.
You should refer to the electronic stores for technical recommendations.
Being a smart consumer, by knowing the facts about HDTV antennas, you will be able to make s
