[QUOTE="DavidW, post: 68509, member: 180532"] I'm sorry Rolf, but my geometry isn't quite as good as it should be. You say the top of the dish must not be higher than the apex of the roof. So, as I understand it, if I mount the dish on the east side of the roof I will not be able to see the further western satellites and vice versa: west side, eastern satellites. If I mount the dish on the end of the house, which, as I said, is North facing, it will have to extend somewhat to be able to point to all satellites. As the satellites around 0° longtitude are fairly high, (my latitude is 51°), the dish will be able to see over the apex. As long as the arc is visable as the roof slopes East and West all should be OK, even down to the 4° elevations which can be seen from the apex. As I said, my geometry isn't too hot but I hope my presumptions are correct. My question is, how far can I extend a 90cm dish from the North wall to be able to point South? Also, what sort of mounts would I need? Would I have to have a light mesh dish instead of a solid one? Perhaps the real question is, is it actually possible? Of course, I could have one dish on the West wall and one on the East but then we are back to the planning problem: two dishes! And the East wall is the front of the house. Please don't suggest that my solution is to move house. [/QUOTE]
