As I know from high school geometry lessons, any 3 points can make up a plane. Extrapolating this clause to satellite hardware language, I could say that star-holder is more than enough to hold LNBF or LNB in perfect position when LNB's Phase center is perfectly co-located with antenna's Focal point. Star-holder allows to do so. And there is no need to overmedicate things .... Points are A, B and C, and their positions are dependent on length of the 3 feedarms (in some cases there are 4 feedarms). I've got several out-of-shelve star-holders, and I've made several myself. Of course, nothing can be better than proper pipe-clamp (made of INOX and wide enough). That is my IMHO. Holder for C-band LNB/LNBF looks more or less same but has another clamp as a central part. Actually, C-band LNB holder is more universal, as it can hold not only C, but also Ku and Ka LNBs, only proper spacers should be used.
