I have a winguard 76cm dish, and am looking at getting the twinhan starbox usb reciever for 4:2:2 programming..... Currently i only have a ku-band xtreme .3 lnbf.............If i bought a c-band lnb for the 76cm dish, would it be possible to pick up cbs-hd off of IA6? or is impossible to pick up c-band programming with a 76cm dish??
