Hi Psolo and the rest of the house? There is a differnce. first, generally ku band lnbs are smaller in size than the c band lnbs. Technically, ku band lnbs receive linear polarized frequencies while the c band lnbs receive circular polarized frequencies.They are non super-imposable. Ku band lnbs are designed to work best on offset dishes while C band lnbs are for prime focus dishes. However Ku band lnbs are also widely used on prime focus dishes. ASAS has pushed Some forum members into trying the C band lnb on offset dishes too. Good evening.Open question.Is there a difference btn a ku band and c band in name or make?
