置。[Claims for Utility Model Registration] A first directional coupler disposed at a transmission output end to supply transmission output to a transmission antenna and branch out a part of the transmission output; and a reception antenna different from the transmission antenna. a second directional coupler that performs reception coupling of a master station signal as a desired wave received by the receiving antenna, and input coupling of a suppression signal that suppresses a transmission output component as a disturbance wave mixed in via the receiving antenna; a level adjuster that adjusts and outputs a part of the transmission output branched out from the first directional coupler to approximately the same level as the interference wave; and a level adjuster that shifts the phase of the output of the level adjuster by 180 degrees. A television relay broadcasting apparatus comprising: a phase adjuster that supplies the suppression signal to the second directional coupler.
