ABSTRACT:
An antenna system is presented herein. This includes an electrically conductive vertical mast radiator. A plurality of top loading electrically conductive wires extend from the radiator. Each wire has an inner end electrically connected to the radiator and an outer end located away from the radiator. The electrical length from the radiator to the outer end of each wire is adjustable to vary the operating frequency of the antenna system.
