A gap filler for DMB(Digital Multimedia Broadcasting) service is provided to freely install the gap filler, easily maintain and manage the gap filler, and efficiently construct and operate a repeating network. A gap filler for DMB service includes a signal processing unit(10), a distribution unit(20), and a power amplification unit(30-1,30-2,30-n). The signal processing unit is connected to a donor antenna, receives a DMB signal from the donor antenna, and converts the received DMB signal into a signal having a form suitable for DMB service. The distribution unit distributes the DMB signal output from the signal processing unit to a plurality of signals. The power amplification unit amplifies the DMB signal output from the distribution unit and transmits the amplified DMB signal through a service antenna. The signal processing unit includes a controller for controlling the gap filler. The distribution unit includes a power supply which generates an operating power based on an external power and provides the operating power to the power amplification unit in response to control data from the controller.
