Some info.....
If a satellite is below your viewing horizon (the Earth is in the way) you would not be able to receive it.
However the satellites he is looking for may be viewable if the dish size is big enough, how big is a question for the size of your pocket book.
Astra 2E has a middle East spot beam, what is on that beam I have know idea, but it is visible at that location, it may not be receivable, but it's visible.
All satellites have a bit of side scatter to the beams used to supply signals to special locations, this side scatter is receivable if the dish is big enough and you have the correct equipment to decode the signals, a 3 meter "C" band dish could be used for "kU" band if the mesh is small enough, and you have a "kU" band LNBF on it, so if you can fit a #2 wooden pencil through the mesh it's too big for "kU" band.
But at your location you would need a much larger dish.
I have a friend that works at a special monitoring site, this site is in South America, he uses the large dish (20 meter) at that location to watch American satellite TV (with a subbed receiver) when he gets the time.
