Knowing More About Antennas

You should try holding out your hand and catch information, words, and pictures passing by. That is more or less how an antenna functions. The antenna is the metal dish or rod that will catch the radio waves and turn them into electrical signals that will feed the radio, telephone systems, or television. These antennas are called receivers sometimes. You need to know that the transmitter is actually another type of antenna which will do the opposite job of the receiver which is to turn the electrical signals to radio waves so that they can travel back and forth to space or travel around the world. It is important for you to take note that transmitters and antennas are the key to almost all types of modern telecommunications today. That is why you should read this article in order for you to know more about them.

You should know how these antennas function.

So let’s say that you are an owner of a radio station and you want to transmit your radio programs to the world, how will you do it? You will have to use a microphone in order to capture the voice of people and turn them into electrical energy. You will take the electricity and allow it to flow into a tall metal antenna. The electrons will be creating an electromagnetic radiation in the form of radio waves as it wiggle back and forth the metal antenna. The radio waves will be travelling at the speed of light and will take the radio programs with them.

You should also know that the antennas and transmitters have the same design most of the time. So if you are using a satellite phone that can receive and send video or phone calls to any place using space satellites, then the signals will be received and transmitted through a satellite dish o ra special type of antenna shaped like a bowl. But most of the time, receivers and transmitters look different. The radi or tv broadcasting antennas are huge and can high into the air for hundreds of feet because they need to send powerful signals over very far distances.

You need to know that waves will not actually zap through the air. There are actually three ways that waves can travel based on the type of waves that you want to send, how far you want to send the waves, and when you want to send the waves. The waves can travel from the transmitter to the receiver by line of sight, bouncing off the ionosphere, or through the ground wave.

That is why you need two antennas in a radio. You should know that the signals on these wave bands are carried by radio waves of various wavelength and frequency. Visit this site if you want to discover more about antennas.
