How do I determin what my focal point is.

[goaliebob99]

How do I determine what my focal point is? I have one of these WS International LNBF's and it has a bunch of numbers from 34-42, and a 7 1/2 foot Wineguard dish. What would I set my focal point to on the LNB and how do I determin if my LNBF is properly centered on the focal point of the dish as a whole. Being that Im getting signal really good on my old LNB, Im assuming that im allready there, but I want to be sure..

Thanks guys

The 7.5' Winegard has a specified focal length of 31.5". Of course many feeds want the focal point slightly inside of them.
