A dipole antenna with folded back ends. Linear conductor elements are fed by a balanced two-wire transmission line which is connected to a balun transformer in turn connectable to a coaxial line. Preferably, the balun transformer is a small device, made of a ferrite donut wound with thin wire and occupying less than one cubic inch. The transformer is preferably located at the feed point and can then be incorporated into the antenna.
