[QUOTE="moonbase, post: 1007199, member: 178786"] I have found that fine tuning the position of a C Band LNB to be quite "fuzzy", the max signal is available over quite a few millimetres of focal length, much more range than Ku Band. Same for the position of the scalar on the LNB barrel. By comparison, the Ku Band signal drops away sharply once the LNB deviates from the sweet spot for focal length. As far as I am aware it is a characteristic of the wavelength, C Band is a lot more tolerant compared to Ku Band. Rgds [/QUOTE]
