Abstract: An end supported antenna having inner and outer elements extending outwardly from a supported end and of which the inner and outer elements each form one element of the dipole. Such antennas are driven centrally of the inner and outer ends or intermediate the ends between the dipoles. There is a decoupling sleeve on the inner element that functions as a coaxial transmission line of variable characteristic impedance on its inside and functions as a radiating element of the antenna on its outside. Generally, one or two sleeves are employed, the sleeves being of non-uniform cross section so as to be either conical or generally conical in shape, flaring from the supported end. A dielectric member separates the inner and outer elements and has an impedance matching network formed therewith. A support pipe extends outwardly from its supporting end to adjacent the impedance matching network.
