Have you ever asked yourself what are the things that make satellite television operate and what are its most important purposes? This short article will hopefully answer some of your basic questions in this matter. First of all, let us establish the basics: satellite television at its basics is the broadcasting of both video and audio signals, sent by the satellites to the dishes which are on the surface of Earth. The satellites are on a geostationary orbit. Indeed, satellites can almost be regarded as a contemporary wonder and they are the ones which make so many things possible, and not only in the field of satellite television. They have revolutionized communications. They orbit the Earth in the Clarke Belt, which is a region of space found 22,300 miles above the Equator line. But now let’s talk a little bit about the transponders. They are objects that broadcast the signal to the Earth, and each and every satellite has a number of them. The signals being carried are different in nature. Most often, they are transmitted on some important bands, the Ku Band, the C Band and the Ka Band. The frequency of the signal is the most important element which is defined by these various types of bands. Bear in mind, the signals must travel more than 20,000 miles, 22,300 more precisely. They are then picked up on the ground by the satellite dishes. A satellite dish’s main purpose is to pick up these signals and transmit them further away. Even if a dish can be as small as 18 inches in diameter, it will still manage to deliver the signal to the feedhorn. And now, in its journey, the satellite signal reaches the feedhorn. But what is the feedhorn? A feedhorn is apart of the satellite dish. The feedhorn’s purpose is to receive the signal and carry it over again to the LNB. Then, the LNB will amplify the signal in order to transform it to a frequency which will be more suitable for a transmission which is done over cable. And now we discuss another unknown term, the LNB. LNB is an abbreviation from Low Noise Block, and its task is the one mentioned in the previous paragraph. The cable is known under the term of IFL, an acronym of Intra Facility Link. The IFL is the object with the help of which the LNB transmits the signal to the receiver. Finally, the last step of this process is done by the receiver, which transmits the signal to your television set. And this is the place where the signal’s journey is finished. It is pretty interesting when you think about all the technology which is involved in this process and all the complicated steps and transformations the signal will need to go through. So now you know at last how satellite television works at its basics.
