The Amazing Technology Of Consumer Satellite TV
Scientific types may want to turn away. This is a very short, yet interesting, explanation of how does satellite TV work. Even though it has become very popular in the last few years, satellite TV has been around for a long time. The first satellite for TV was put into orbit in’62.
When it all started there were not a lot of satellites up and most people who wanted to get satellite television had huge gray satellite dishes planted in their back yards. There are still some of these around. They are usually about nine feet in diameter and when somebody wants to move the dish to get a different country’s programs it is a group effort. They originally came with remote controls, but those were lost several years ago so the dish gets turned manually.
At that time, and for several years after, no one who owned the dishes really knew which satellites were plugged into which countries. So, you would move the dish until you picked up a country that looked good and watch it for a few days or months until you moved the dish again. Sometimes you landed on your own country, most times you didn’t. But, it was fun and all countries have unique television programs that aren’t seen in other countries.
