A question;
the Focal length for the Ku band is the same as for the C band.
Because you see the majority on the Internet for the C-band

Best regards

You've started on the sauce a bit early.

Focal distance is independent of wavelength at the frequencies mentioned.

I am building a construction. And then it would be nice if you know what the dimensions are.

The focal distance of the feed rim opening aperture from the dish for maximum signal level are different for C-Band and Ku-Band
 
Here are two photos of my system and how the LNB' stand because of the focal length, I'm currently at 40.5W and watch Formula 1 on FS1 :D

@MrDish1 - you really could do with reading up on things before asking questions way beyond your current understanding. Most of the time, I have no actual idea of what you're even asking as there is no context, no sense and, like CH says, no question marks.
