How Satellite TV Works

Gone arerepparttar 138203 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 howrepparttar 138204 antenna broadcasting system works. Traditional television broadcasting antennas use radio waves to transmit their programming. Each broadcasting station operates at a unique frequency that identifiesrepparttar 138205 station torepparttar 138206 FCC and allows your receiver to select a particular “channel”. These radio waves are carried fromrepparttar 138207 station’s antenna to yours which, when tuned torepparttar 138208 specific frequency picks uprepparttar 138209 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 betweenrepparttar 138210 two points of communication.

Enterrepparttar 138211 Satellite

A satellite is actually any object that orbits a larger object, such asrepparttar 138212 Earth. Our Moon is considered a satellite and, in theory,repparttar 138213 Earth would be a satellite torepparttar 138214 Sun. Man-made satellites follow this same premise. A man-made satellite is placed into position just over 20,000 miles aboverepparttar 138215 Earth. It is programmed to orbitrepparttar 138216 Earth so thatrepparttar 138217 satellite stays in sync withrepparttar 138218 Earth’s rotation. This means that a satellite that is positioned overrepparttar 138219 United States will stay overrepparttar 138220 United States, despiterepparttar 138221 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 offrepparttar 138222 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 thatrepparttar 138223 traditional broadcasting system uses but at 20,000 miles overrepparttar 138224 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 whatrepparttar 138202 best choice really is. The best choice may lay in these factors:


Both Cable TV and Satellite TV are popular. Although cable still is more popular overall, satellite TV has made huge gains on cable TV.


Cable TV systems require a cable to be installed fromrepparttar 138203 network to your house. If your street has no cable you may need to wait a while before it is available in your area. Besidesrepparttar 138204 cable you need a receiver. With digital services you need an additional box.

Satellite TV requires a satellite dish, a receiver and a cable fromrepparttar 138205 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 allrepparttar 138206 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.
