PURPOSE: An apparatus for preventing the attenuation of power line signals is provided to prevent the attenuation of a multi communication signal inputted to a power line communication equipment by being combined to an outlet of a power line communication system. CONSTITUTION: An apparatus for preventing the attenuation of power line signals comprises a power line-side connection terminal(603), a filter part(605), and a power line communication equipment connector(611). The power line-side connection terminal(603), connected to a power line side, receives power and communication signals through the power line. The filter part(605), connected to the power line-side connection terminal(603), passes a necessary power line signal frequency and attenuates an unnecessary frequency. The power line communication equipment connector(611), connected to the filter part(605), transfers the power and power line signals outputted from the filter part(605) to a power line communication equipment side.
