Firstly can you let me know where abouts you are, so that i can make sure I cover the area, and if not I can recommend someone to you.
Secondly, before anything gets done you will need to make sure you have permission from the appartments community / presidente that a dish can be installed.
Thirdly, it may be best to discuss individual installations via email rather than on an open forum...
mail me at
and i shall get back to you when i can....
