The motor or positioners of C-Band dishes usually require 36V for power. Most FTA receivers do not supply this, so you need to add a V-Box or G-Box or something of the like. These "boxes" convert the DiSEqC motor positioning commands to something that the motor on a C-Band or "BUD" dish can use. Basically it is a "go-between" or power converter in a manner of speaking.
