Description
CQ出版株式会社 別冊CQ ham radio 3月号1993年3月1日発行ダイナミック・ハムシリーズ16「ワイヤーアンテナ」p205「6.10 7MHzダブル・バズーカ」
2 電気的長さが1/4λの同軸ケーブルに相当した長さの金属管(パイプ)
3 給電ポイント、インピーダンス及び不平衡・平衡の変換をバランにて行い送信機へ
Claims (1)
- アンテナの放射器(ラジエーター)として速度系数(短縮率)を乗じた長さの1/4λの同軸ケーブル二本を直線上に配し両端の内部導体(芯線)と外部導体(外被線)を短絡し、中央部はそれぞれの向かい合う内部導体(芯線)と外部導体(外被線)を交差させて接続し、中央部の接続点を給電部とし、それぞれを金属管(パイプ)内に配し、先端部と中央部は金属管(パイプ)に接合してインピーダンス変換バランを介して給電する通常の必要とする放射器(ラジエーター)長を同軸ケーブルの速度系数(短縮率)を乗じた長さの放射器(ラジエーター)長で実現した短縮型のダイポール型アンテナ装置。
