成ることを特徴とするテレビ中継放送装置。[Claims for Utility Model Registration] In a television relay broadcasting device that receives a master station signal with a master station signal receiving antenna, and transmits a self-transmitted signal from the transmitting antenna using a channel adjacent to the receiving channel of the master station signal as a transmitting channel, a local station signal receiving antenna that receives the local station signal; and a signal received by the local station signal receiving antenna at the same level as the local station signal received as an interference signal by the master station signal receiving antenna. a level adjuster that adjusts and outputs the output, a phase adjuster that inverts the phase of the output of the level adjuster by 180 degrees, and synthesizes the output of the phase adjuster and the output of the master station signal receiving antenna. A television relay broadcasting device comprising a directional coupler or a 3dB coupler for outputting.
