Editing Brief Review On The Antenna

<br><br><br>Antenna is Used to Receive Signals<br> <br>Hunan being invented the antennas long time ago and it has been produced by antennas manufacturer and used by us for a long time period. Usually, we use it to receive the signals for our TV and radios. For TV and radio, we have to use the antennas to transmit and receive electromagnetic waves, otherwise, our TV set and radio set cannot pick up signals from the stations. As a matter of fact, the strength of the antenna as well as how to pick up the signals are greatly decided how many channels you TV set and radio set are able to pick up. Besides that, where your antenna locate, its quality and the weather also can exert the influences on the quality of the transmission and the number of channels your TV set and  [https://www.kynghidongduong.vn/tours/tour-trung-quoc-nam-ninh-truong-gia-gioi-phuong-hoang-co-tran-6-ngay.html tour phượng hoàng cổ trấn] radio set can receive.<br><br><br>(adsbygoogle = window.adsbygoogle || []).push();<br><br>Working Principle of TV Antenna<br> <br>We can see the TV antennas that are set indoor and outdoor. Usually, the indoor antenna is also referred to half wave dipole antenna which features small size. These indoor antennas make full use of its "ears"to adjust the lengths to improve the strong signals. But the fact is that these indoor antennas are not good as those mounted on the rooftops or outdoors. The outdoor antennas are usually bigger in size and can receive strong and better signals. The only [http://www.ehow.com/search.html?s=disadvantage disadvantage] of these antennas is that the weather can easily affect the signals. For instance, the strong wind outside would change the location of the antenna so that the signals would be disrupted. In this case, you can set the TV antenna on the highest windows of the building or on the attic to cope with the problem. You would spend more to take the downside of outdoor  [https://www.kynghidongduong.vn/tours/tour-trung-quoc-nam-ninh-truong-gia-gioi-phuong-hoang-co-tran-6-ngay.html kynghidongduong.vn] antennas. Also, the distance of your location and the transmitter would affect the quality of the signals. You would pick up better and strong signals if you stay close to the transmitter.<br> <br>Working Principle of Radio Antenna<br> <br>The working principle of a radio antenna and a TV antenna is roughly similar - change the electric currents into the radio waves and vice versa. It also has a transmitter and a receiver just like TV. Its transmitter uses radio frequency current to the terminals of the antenna which radiates these radio waves (referred to electromagnetic waves too), so the signals can be transmitted. The reception process of the TV antenna and the radio antenna is similar - using the terminals to detect the signals and receiver decodes can be amplified.<br> <br>You could find more information on ante[ ][ ]<br><br><br><br><br><br><br><br>(adsbygoogle = window.adsbygoogle || []).push();
