why is a sattelite dish shaped the way it is?
How come there aren't a lot of unwanted signals intercepted?
How does weather affect a signal?
HOW CAN A SATTELITE SEND SIGNALS TO A WHOLE BUNCH OF DISHES AT ONCE?
Those type of things are what i am looking for.
The info i am looking for is for my science fair projecet, but i can't 
find anything anywhere!!!! I've tried lots of sites. what i want is not 
nececerraly the answers to my question so much as links i can follow to 
get to some decent info.
