Abstract: On the training ship "Nagasaki-Maru", the inductive voltage on the receiving antenna caused by the transmitted electric waves was extreamely high. The inductive voltage resulted from the construction of ship with the restricted length of sending and receiving antennas. Since such an extreamely high inductive voltage was harmful to wireless service on a medium wave and a 4 MHz wave, the inductive voltage was measured and a preventive method therefore was devised. When the sending and receiving antennas were stretched in parallel, the induction to the receiving antennas was extremely high. And when antennas Nos. 2 and 3 were used as receivers and antenna No. 1 as a transmitter, the inductive voltage was higher on antenna No. 3 in case a condenser was infixed to antenna No 2. Therefore, in order to meet the demands of the times, a whip-typed receiving antenna is thought to be desirable. / 送受信アンテナを平行に展張した際の受信アンテナへの誘導が非常に高い。またNo.2およびNo.3アンテナを受信用にし,No.1アンテナで送信した場合,No.2アンテナにコンデンサーを挿入すれば,No.3アンテナの方が誘導電圧は上昇する。したがって時代に即応するためには,受信アンテナのホイップ化が望ましい。
