Just for yucks, I made up the following pictures to help explain to brother what we mean here. He is obviously a complete newbie and need some basics.
First of all brother, you have a satellite DISH, not a satellite. The satellite is about22,300 miles above the Earth's equator. The degrees mentioned here mean "degrees longitude".
Attached are what the satellite can see from 9° east, 9° west, 89° east and 89° west.
I hope these can help you better understand what is being discussed here
See ya
Tony
