Hi:
My question is, for example, I need a specific angle to see the dish (95 °, 80 ° or 74 ° ........) and I wanted to detail the Vidhorn manually
So what measurements are in use, please.
Is there a program to extract measurements
............................................
Why is the angle of the inverto approximately 80 degrees and when measured, the angle of the angle is approximately 63 degrees?

That is because Phase center of the feedhorn located inside the feedhorn. And one of the main parameters of the feedhorn is it's illumination angle (between green lines) and not opening angle (between red lines). ScreenHunter 101 Dec 05 2038

Thank you my friend.
Is there an equation to calculate the tendency of the Fidhorn angle?
