[QUOTE="davemurgtroyd, post: 957823, member: 319227"] Aimed at a satellite on the main axis the focal point is a certain distance from the dish along that axis, with off axis satellites is that distance still the same? If so the mounting bar needs to be curved and not perpendicular to the main axis or if it were straight then the lnbs would be further from the dish. Also do lnbs not need aiming at the centre of the dish (and not parallel to the main axis) - simple angle of incidence equals angle of reflection [/QUOTE]
