HDTV antennas have become necessary items in our life today as many nations now completely broadcast television in high definition. The antennas allow us to view high-quality television shows easily. Before you buy an antenna, you are reminded to make your choice carefully. You can't simply get any antenna as it might not match your digital television due to unusual factors. Having certain knowledge about antenna is necessary.
In order to save your time looking for information related to an antenna, We have summarised some important facts here. You can take the points below as a reference.
• First thing first. Why do we need HDTV antennas? What is the difference between high definition and standard definition? For your information, the HDTV antennas enable more than 1000 lines of colour to be transmitted. However, for standard definition, just 480 lines of colour are transmitted. In other words, the more lines of colour are transmitted, the finer image quality you can obtain. Now, you should know why so many people are madly talking about HDTV and its antenna. If you want to watch the free broadcast, it is for certain that you need the antenna to get a clearer picture. However, if you are the subscriber to satellite or cable, you are not obligated to fix an antenna. You will be able to watch shows in high definition automatically.
• There are many kinds of antennas in the market. They have various functions and features. They come in different sizes. Some miniature antennas look like rabbit ears. You can also find big rooftop models. The size of an antenna influences the image quality of the television shows. The larger the antenna is, the better the reception.
• Besides the size of the antenna, its location also plays a vital role. If you want to have a better view, you need to position your antenna at a location where there is no any interference. You are reminded to avoid setting your antenna at the place where there is high building in front. If it can't be dodged, then you would have less chance of having a good image quality.
• HDTV signals are transmitted over the same frequencies as analogue signals. If you already have a conventional antenna with you, you don't need to waste more money to get a new HDTV antenna. You are expected to get a converter box to pick up the HDTV signals. However, if your standard antenna is exceedingly old-fashioned, you may not be able to watch the programs in high definition. If this is the case, you need to get an HDTV antenna to resolve the issue.
• Not all digital TVs are able to match with the HDTV antennas. These antennas pick up TV broadcast with a full 16:9 aspect ratio. If you are watching the shows with black bars on the bottom and the top of the image, it confirms that your television does not have a widescreen display. You should go to the electronic stores for technical instructions.
