[QUOTE="bignick, post: 406940, member: 190163"] F/d does not change with the diameter of the dish. It is a ratio of sorts between the depth and diameter of the dish. Please check out [URL]http://www.satellite-calculations.com/Satellite/reflector.htm[/URL] to see. Think of drawing a circle with a set of compasses - the pin end would stay the focal piont no how long you draw the line - of course that only works for less than a half circle in satellite terms :) Cheers Nick [/QUOTE]
