If he can in the first place. For KU-band, usually a small dish (40-120cm) is used. That's consumer (DTH, Direct To Home) stuff. With the C-band, you have usually have to start thinking 180cm and up, and a different (probably more expensive) LNB. In Kaffeine, you can configure a C-band LNB. I've never tried it, I don't have enough space to set up a dish for the C-band..
