[QUOTE="BrianWheatley, post: 899102, member: 402768"] Hello, I have a 144 inch dish, with 24 inch depth. According to the Focal Length calculation (D*D/16*d) I should have a focal length of 54 inch. However the current set up has Feed legs that mount the scalar rings to 58 inches. A 4 inch offset is huge when dealing with microwaves. I am scratching my head why it is 4 inches off. Has anyone heard of this before?? Ps- sorry for the imperial units... the Americans have brain washed me :) [/QUOTE]
