How does a satellite dish recive its signals to let you watch television?
Answer:
Well..It uses a SUPER High Frequency to carry Digital signals to the satellite dish for processing.The super high frequency is designed to penetrate clouds better.
When this signal hits the bowl-shaped dish, the dish's "bowl shape" focuses the signal into the amplifier called the LNB...that's that can or square box about 2 feet away from the Dish.That LNB takes the signal, strips off the Super High frequency leaving up to 400 channels of digital signal...that is then sent to the box and the box picks up all 400 channels and lets you select which channel you want to watch.
Once the signal gets to the box, the box takes the Digital signal and builds a Picture with it.and the Digital Audio is converted too.
Now I can get into a lot of DETAILS, and bore you for days to come.but that's not why you asked the question. Now you have the basics needed.
The dish picks up a very high frequency signal that is so weak it takes an active amplifier at the dish to build up the signal enough to send it on the the receiver that breaks the signal down to a lower frequency which is eventually made viewable by a TV receiver.
