Salam alaikum:
Ma question est, par exemple, j'ai besoin d'un sous un certain angle (95 ° ou 80 ° ou 74 ° ........) et je voulais en faire un manuellement les mesures utilisées pour le travail, s'il vous plaît.

Pourquoi est l'angle de l'invertébré 80 ° et en mesurant l'angle de l'angle du capteur, nous trouvons environ 63 °?

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?

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).

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