Abstract

PURPOSE:To radiate various kinds of electromagnetic wave different in wave length simultaneously without mutual interference by utilizing one base-grounded iron tower. CONSTITUTION:Arm metal U to suspend conductor F2 of an approximately lambda2/2 height through insulator I is provided in the side of base-grounded iron tower T having an approximately lambda1/2 height. Iron tower I is provided with feeding point t1 at the position having an approximately lambda1/4 from the ground, and filter circuits Q2 1 whose series resonance and parallel resonance are tuned to lambda1 and lambda2 respectively are mounted on the way of feeding conductor F1, which connects point t1 and transmitter TX-1, at a proper interval. Filters Q2 1 whose series resonance and parallel resonance are lambda2 and lambda1 respectively and reactance element X2 to prevent the iron tower upper part and conductor f2 from being affected by electromagnetic waves of lambda2 are connected to conductor f2 which falls to the ground from point t2 having an approximately lambda2/4 height from the base of iron tower T. The filter Q2 1 above is mounted on conductor F2, and transmitter TX-2 which outputs the excitation power of wave length lambda2 is connected to the lower end of F2.
