A few years ago, before DISH Network and DIRECTV launched their direct broadcast satellite companies, dishes were humongous - up to 9 feet in diameter. But now, thanks to modern technology, they're smaller than a saucer sled. Here's how satellite TV dishes work and where you can get one free.
What is a satellite TV dish?
A satellite dish is a round parabolic reflector, shaped like a saucer, that picks up TV signals. These dishes are typically 18 inches to 31 inches in diameter and made out of aluminum so they won't rust. They are aimed at a satellite hovering 22,300 miles above the equator that broadcasts TV signals down to earth.
Between the two major providers, DISH Network and DIRECTV, there are more than 25 satellites in orbit above the earth that broadcast more than 500 channels of programming to more than 27 million subscribers.
How does a satellite dish Work?
The curved satellite dish focuses the signal sent from a satellite to a feedhorn, that funny looking arm that sits in front of the dish. The feed horn amplifies the signal and sends it to a receiver. The receiver then converts the signal into audio and video signals and sends it to your TV.
Where can I get a free Dish?
Both DISH Network and DIRECTV will give you a free satellite TV dish if you sign up for one of their program packages. They'll also give you a four-room receiver system, universal remote controls, and free installation. Program packages start at less than $20, which is a pretty good deal if you're thinking about switching from cable or over-the-air TV.
