[QUOTE="a33, post: 1093500, member: 332642"] To add to my previous post: In the article I also describe an equation to calculate the [I]offset angle[/I] for an offset paraboloid dish, that has a [I][B]non-flat dish face[/B][/I]. Finding this offset angle, is needed to be able to calculate the focal length and other dish specifications. For the calculation of the offset angle, only four input measures are needed. There is no need anymore to use the 'water method', that is described in the article of John Legon. So again, I think the measurement phase for finding all the dish specs is much easier. The equation is: [ATTACH type="full"]131892[/ATTACH] Again: enjoy the use of this equation! Greetz, A33 [/QUOTE]
