How Satellite TV Works
Gone are days where you could spot a satellite dish six blocks away. Today’s dish is drastically smaller, much more reliable and considerably less expensive than its enormous ancestor.
So, just how does Satellite TV work?
First, you need to understand how antenna broadcasting system works. Traditional television broadcasting antennas use radio waves to transmit their programming. Each broadcasting station operates at a unique frequency that identifies station to FCC and allows your receiver to select a particular “channel”. These radio waves are carried from station’s antenna to yours which, when tuned to specific frequency picks up waves for your television to interpret and project.
Unfortunately, radio waves can only travel so far when emitted from an antenna and are subject to distortion as objects get in between two points of communication.
A satellite is actually any object that orbits a larger object, such as Earth. Our Moon is considered a satellite and, in theory, Earth would be a satellite to Sun. Man-made satellites follow this same premise. A man-made satellite is placed into position just over 20,000 miles above Earth. It is programmed to orbit Earth so that satellite stays in sync with Earth’s rotation. This means that a satellite that is positioned over United States will stay over United States, despite Earth’s constant movement.
These man-made satellites are electronic boxes that contain a communication system, a power source and a navigational system. Many satellites use rechargeable batteries as their power source, feeding off Sun’s natural energy source via large solar panels. The communication system is designed to relay information back and forth through those same radio waves that traditional broadcasting system uses but at 20,000 miles over Earth, satellites have a much better range than a regular antenna and aren’t as affected by trees, buildings and other objects that might obstruct a traditional antenna’s path.

There's a battle going on between Cable TV and Satellite TV. Many people wonder what best choice really is. The best choice may lay in these factors:
Popularity Both Cable TV and Satellite TV are popular. Although cable still is more popular overall, satellite TV has made huge gains on cable TV.
Equipment Cable TV systems require a cable to be installed from network to your house. If your street has no cable you may need to wait a while before it is available in your area. Besides cable you need a receiver. With digital services you need an additional box. Satellite TV requires a satellite dish, a receiver and a cable from dish to your TV (no digging in your garden).
Reception Quality Cable TV has analog channels and even though you can upgrade to digital services, analog channels will still be analog, meaning an often fuzzy picture. Satellite TV is completely digital, which gives you all advantages of digital systems. Very heavy rain or snow can obstruct reception briefly, but generally this happens very rarely. Reception quality is much better with Satellite TV.
