AnixOOO:
What do you mean by "RING"?
180cm dish, is it prime-focus or offset? If prime-focus than ring could be used for better reception, but LNB should be changed as well.
Anyway, with simple circular Ku-band LNB you can not receive C-band signals! Who said you opposite? So, if you have 72% without ring, than if you put any ring, on C-band you will get 0%.
