How does Satellite TV Transmit?
The main way satellite television works is by sending digital video and audio transmissions from satellites in Earth's orbit to other satellite dishes that are somewhere on the surface of the Earth. Satellites used for broadcasting TV are in an orbit of the earth and located in a region known as the Clarke Belt about 22,000 miles above the Earth's equator. The satellites used in sending TV signals to the Earth have several transponders. Each transponder sends a separate signal to Earth. The satellite signal has to travel more than 20,000 miles from the provider to get to the satellite in the sky. Then the signals are sent back again, another 20,000 miles, and transmitted by a satellite dish. Satellite dishes that receive television signals range in size from 18 inches all the way to 9 or more feet across. Most satellite television providers us a dish that is only 18-20 inches across. The television programming signal is collected by the satellite dish and the reflected to a feed horn. Then the feed horn sends the signal to a LNB or a Low Noise Block down converter. The LNB amplifies the transmission signal and converts it into a frequency that is easier for transmission through a cable. Then the signal goes to the satellite television receiver. From there, the signal is sent to your TV set from the receiver. And finally, the signal goes from your television to your brain.
Benefits of Satellite TV
There is no problem with range or distortion like there is with cable television because satellite television transmits signals from satellites orbiting the Earth. With a satellite being high in the sky, many more people are in direct line of sight of the transmission. Because the satellite is in the same orbit, it is only necessary to aim the dish at the satellite one time, and from then on it doesn't need adjusting to pick up the TV signal.
Getting Satellite TV
To get satellite television, you will need to subscribe to a provider that offers the programming in your area. If you are not sure which service would be best for you then you should compare several providers before placing your order. You can usually order services online or over the phone.
