Claims (4)
- 共同受信装置の線路を伝送され、テレビジョン受信機で受信可能なものを含む高周波信号を増幅する中継増幅器において、
この中継増幅器のモニタ出力信号として、分岐器または方向性結合器によって分岐させた分岐信号を出力するモニタ出力部と、
モニタ端子と、
前記モニタ出力部と前記モニタ端子との間に設けられ、第1の状態と第2の状態とのうち選択されたものに切換可能な可変減衰手段とを、
具備し、前記可変減衰手段の第1の状態は、前記モニタ出力信号が正常なとき、前記モニタ端子に接続したテレビジョン受像機の適正入力レベル範囲内の高周波信号が前記モニタ端子に生じるように設定され、第2の状態は第1の状態よりも大きな減衰量であって、前記モニタ端子に接続したモニタレベル測定器でモニタ可能なレベルの高周波信号が前記モニタ端子に生じる減衰量に設定された中継増幅器。 - 請求項1記載の中継増幅器において、第1の状態が非減衰状態である中継増幅器。
- 請求項1または2記載の中継増幅器が棟内増幅器である中継増幅器。
- 請求項1、2または3記載の中継増幅器は、高周波増幅段を有し、前記モニタ出力部は、前記高周波増幅段の入力側に設けられている中継増幅器。
