Abstract

PURPOSE:To facilitate the construction and maintenance of a transmitting antenna and to minimize interference between transmitters by supporting a pole grounded at its base with stays having no insulator inserted, by extending several feeders from the apex, and by using lower ends as energizing points for respective waves. CONSTITUTION:Pole H which is lower than a half the shortest wavelength among those of waves to be shared and is grounded at its base is supported with stays G1'-G1''' with no insulator interposed. From the apex of pole H, feeding conduc- tors F1 and F2 as many as said waves are extended down and respective lower ends are isolated from the ground and used as energizing points A1 and A2 for individual waves. Further, circuits Q1 2 and Q2 1 which have infinite impedance to the corresponding waves and no impedance to the other wave are interposed between those energizing points A1 and A2 and the ground.
