Yep, I fully realize that. But I have read postings from people before who use a large KU dish for
C-Band analog audio and it works just fine for them. I've also seen people who have used a 4' dish (120cm) for C-band analog tv signals and it works on the stronger birds who have an eirp of over 42 or 50 I believe. So I know it can be done just looking for how. But I'm thinking the 4' dish might possibly be a prime focus dish so as I said I'm not exactly sure how it was done.
