The satellite itself uses a dish similar to your own satellite dish, to receiverepparttar video and send it back down to Earth torepparttar 138199 provider’s subscribers. The satellite contains numerous transponders, components that allowrepparttar 138200 satellite to pick uprepparttar 138201 broadcast signal, amplify it and resend at a specific frequency. In addition torepparttar 138202 transponders, satellites typically have several other onboard components, including a power source such as solar panels or rechargeable batteries and a computer system to monitorrepparttar 138203 satellite’s various functions and conditions.

Whenrepparttar 138204 satellite sendsrepparttar 138205 signal back down to Earth, it is picked up by your dish, a small round antennae that receivesrepparttar 138206 satellite’s broadcast and sendrepparttar 138207 video on to your satellite TV receiver.

The receiver is that little black box that sits inside your home and allows you to choose which channel you want to watch. The receiver actually performs several crucial functions inrepparttar 138208 satellite viewing process, includingrepparttar 138209 decryption ofrepparttar 138210 signal itself. If you’ll remember,repparttar 138211 satellite signal was scrambled byrepparttar 138212 provider to protect it from un-paying consumers. Your receiver “de-scrambles” that signal and convertsrepparttar 138213 signal into a format that your television can handle, such as analog or more recently, HDTV.

Together these amazing components create a vividly clear digital picture for over 200 satellite channels. How’s that for programming genius?

The good news is that you can usually find this information withrepparttar help of your satellite provider. DISH Network for example features a Point Dish/Signal option in their on-screen menu to assist you inrepparttar 138198 adjustment of your dish. Using your zip code, you can determinerepparttar 138199 azimuth, elevation and skew. Pointing your dish is normally part ofrepparttar 138200 installation process so plan to do your install when you have time to follow through.

Your skew should be set before you mount your dish. Usingrepparttar 138201 adjustment number from your service provider, rotaterepparttar 138202 dish horn to matchrepparttar 138203 recommended coordinates.

With your azimuth and elevation numbers in hand, grab your compass and go outside. Standing close to your dish but at least one foot away, rotate your compass untilrepparttar 138204 needle points North, or zero degrees. Starting from this point, locaterepparttar 138205 azimuth number onrepparttar 138206 compass and turn to face that point without movingrepparttar 138207 compass itself. East is 90 degrees, South is 180 degrees and West is 270 degrees. If your azimuth number is 240 for example, you would face a direction that fell between South and West on your compass.

Now that you’ve found your direction, estimaterepparttar 138208 angle of elevation. Withrepparttar 138209 ground representing zero, calculaterepparttar 138210 distance going upwards usingrepparttar 138211 elevation number provided by your provider. Straight up would be 90 degrees so if your elevation number was 45, your elevation would be halfway betweenrepparttar 138212 ground and looking straight up intorepparttar 138213 sky. Got it? Good... There’s your satellite!
