Satellite dish TV - how does it work?

When it first hit the market with the use of satellite dishes for television in the early 1990s, the home dishes were a very expensive metal objects that took up a huge space on the yard. In these years during the launching of satellite TV or satelit TV, only the die hard fans would go to extra lengths in obtaining and spending extra money just to have a satellite dish to connect to various channels at home. When it comes to having a satellite TV or cable TV it was quite hefty and expensive for the pocket of an ordinary individual.

Compared today, you tend to see a lot of satellite dishes mounted or installed on different roofs of every houses you see. Even around the rural areas of the country that has no cable TV provider, you can see a lot of satellite dishes installed on their rooftops. Much of the major satellite TV companies are luring in more consumers each day with news, sporting events and movies from different areas around the world.

The Satellite TV system or the satelitTV processes are broadcasting audio and video signals from geostationary or satellites that have the elliptical orbit that transfers signals to different satellite dish of the terrestrial plane of the earth.
• The satellites that are in a geostationary or elliptical orbits are orbiting the earth in the region of the space namely Clarke Belt which is almost 22,300 miles away from the equator of the earth. Each of these satellites carries with them a few transponders which will carry the signal to the Earth.
• These signals that are from the transponders are particularly Ka band, C Band and the Ku Band. The band that identifies each is the frequency types. After traveling over 20,000 miles the signals from the transponders are received by the satellite dish. The satellite dish can have the diameter of 18 inches or 9 inches. The sole purpose of satellite dishes is to be a reflector and collector. The dish first collects or gathers the signal then reflects or mirrors them to the feedhorn.
• The feedhorn then receives the mirrored signal then sends it to the LNB. The LNB then amplifies the signal and then alters the signal to a frequency compatible for transmission to the cable. The cable used to transfer this frequency is also called as IFL.
• LNB transfers signal to the IFL cable to the receiver of the satellite. The receiver of the satellite then sends the signal to the television set.
