First of all, if you have 60 cm ku band dish, the chances are very less. 1. you need one C-Band universal LNB to receive C band channels.2. Dish Antenna - 90 cm / 120 cm, I managed to get 5 satellite signals including C band by 120 cm dish antenna.there are some satellite dish antenna available in market with 2 lnb (one KU one C band) fitting options. you will also need "DiSEqC Switch" With the help of this switch you can use both LNBs alongwith single receiver. One dish i had named Apana DTH.
