Abstract

PURPOSE:To obtain an antenna of efficiency of radiation by extending conductors downward from the top of a steel tower or its adjacent point with lower ends isolated from the ground and by electrically connecting them to the steel tower via phase shifters. CONSTITUTION:While base M is insulated by base insulator 11, steel tower 10, a quarter or less as high as wavelength (lambda), of an in-use radio wave, is stood and through matcher 12 connected to base M, high-frequency electric power is supplied to steel tower. From the top or its adjacent part of steel tower 10, upper stays 131 having insulators 141-14n interposed at halfway points are extended radially and downward and stays 131' between insulators 141 and 142 are permitted to function as radiating elements 15. Further, steel tower 10 has insulators 14 interposed at its intermediate stage B and lower stage C and lower stays 132 and 133 are extended similarly. Then, phase shifter 16 is provided at top A of steel tower 10 is connected to upper stays 131, connected mutually via connection conductors 172, by using connection conductor 171.
