With 99% of the analog channels gone, I have given serious thought into a C/Ku lnbf system to use 13/18v switching isntead of using a polorotor and the old C band remote to change polarity. Would perfer having a dedicated line to feed C and one for Ku, but the ones I have seen use 22k switching to change bands. Since I have a 22K switch inline already, this would not work. Would be a nice upgrade to the dual feed feedhorn unless I can just bolt on a C lnbf and a ku lnbf in place of the lnb's. Current feedhorn assembly is a chapparal
