ABSTRACT:
An antenna system is presented including an electrically conductive radiating mast that extends generally vertical relative to earth ground. The mast has a lower end for receiving RF energy for radiation thereby at an operating RF frequency and an upper end. A plurality of N radial, electrically conductive, wires are provided with each having an inner end and an outer end. The inner ends of the radial wires are electrically connected together and located proximate to the vertical mast. The radial wires are elevated throughout their lengths above the level of earth ground and extend radially outward from the vertical mast. A tuning device, such as an adjustable inductor, is connected to the radial wires for adjusting the impedance thereof such that the radial wires resonate at the operating frequency.
