Abstract

PURPOSE:To radiate various kinds of electromagnetic wave different in wave length simultaneously without mutual interference by utilizing one base-grounded insulated iron tower. CONSTITUTION:Transmitter TX-1 which outputs the power of wave length lambda1 is connected to feeding point t1 of the base of base-grounded insulated iron tower T, which has an approximately lambda1/2 height, through filter Q2.1 whose series resonance and parallel resonance are tuned to lambda1 and lambda2 respectively, and further, feeding point t1 is grounded through reactance element X2 to restrain filter Q2.1 whose series resonance and parallel resonance are lambda2 and lambda1 respectively and iron tower T from tuning to electromagnetic waves of wave length lambda2 and resonating. Transmitter TX-2 which outputs the excitation power of wave length lambda2 is connected on the way of conductor F2 of an approximately lambda2/2 height, which is suspended from the tip of arm metal U provided in the side of iron tower T through insulator IA, through the filter Q2.1 above.
