"The masthead power supply provides a 12V dc supply via a coax cable, to drive a masthead amplifier. The amplified signal then feeds down that cable and passes through the power supply, and onto the receiver. Choosing to use a separate power supply and masthead amplifier delivers a number of benefits."
