I think the equivalent is that of a normal offset dish with the same height. If the elliptical is 30 inches tall. the equivalent would be a normal offset 30 tall and around 27-28 wide.
I always wondered how much of the dish was actually being illuminated by a regular LNB aimed directly at the center of the dish
My 84e elliptical paled in comparison to my 30 inch offset dishes performance. That was until I put the proper feed horn/LNB on it.
