Abstract
A coaxial antenna includes a vertical half-wave dipole with a lower section in form of a sleeve and an upper section in form of a first conductor bar, with the sleeve being dimensioned so as to resonate at a first frequency or first frequency range. A second conductor bar is operatively connected to the free end of the first conductor bar to define an assembly of first and second conductor bars which is dimensioned so as to resonate at a second frequency or second frequency range.
