Satellite TV Systems - Great Home Entertainment
In the old days of satellite TV systems you would see great big Satellite Dishes in some people's yards. But today satellite TV systems are more common (and smaller) than ever before. They aren't likely to go away any time soon, but they are likely to get better.
systems no longer require great big dishes that stick out like sore thumbs in every neighborhood. In fact, dishes are commonly found neatly hooked to roof tops and perched on balconies throughout the country.
Once very expensive, satellite TV systems are getting increasingly affordable. In fact, some companies actually offer the equipment for satellite TV systems free with a signed contract that guarantees you will continue to pay for satellite reception for a certain amount of time. Before you sign up for satellite, research the freebies your satellite company is willing to offer. If you get a better offer from one than another, give the first company a chance to counter offer. They're not giving people complete satellite TV systems out of the goodness of their hearts, they genuinely want your business and recognize that over a period of years they will more than recoup the cost of the equipment they donated to your worthy television cause.
Satellite TV systems are wireless systems that deliver television programming right to the viewer's home - after the programming has traveled 22,300 miles or so into space and back that is. That's right, your television programming travels to space and right back to your home for your viewing pleasure. Television satellites are all in geosynchronous orbit. Basically that means that satellites stay in one place in relation to the earth and rotate with it. You shouldn't have to adjust your satellite dish once you get it in the right place to begin with.
Each television satellite is launched into space at about 7,000 miles per hour. Satellites revolve around the planet once every 24 hours. Because satellites rotate with the earth, that's the same time it takes for the earth to make one full rotation. Compressed programming signals are sent to the satellites in space, the satellites decode those signals and send them right down to subscribers' satellite TV systems! As you can imagine, the signals are pretty weak after traveling so many thousands of miles so your satellite TV system re-enhances them and puts them into a readable format that appears on your television screen.
