I have excellent c band performance and good ku. Ku is nearly as good as the corotor I removed. My analog box died and didn't ha e anyway to switch the polarity. Using my pansat 9200 I am seeing some 97w ku transponders in the mid 80's while some are down around 55-65% quality. That's the best I could get out of it tweaking and tuning on the hail damaged 10' Sami.
