PURPOSE: A power line radio frequency signal repeater is provided to secure a power line communication network with a wideband, regardless of frequency bandwidths. CONSTITUTION: A power line radio frequency signal repeater is composed of a combiner(20), a specific band filter(30), and a radio frequency signal inserter(40). The combiner(20) receives a communication information signal(10) and amplifies the received signal. The specific band filter(30), connected to the combiner(20), separates only a necessary bandwidth from the signal. The radio frequency signal inserter(40) tunes the signal output from the specific band filter(30) and inserts the tuned signal into a power line(50).
