            BROADBAND MONOPOLE ANTENNA FOR SHORTWAVE RADIO BROADCASTING

            GENERAL DESCRIPTION


            The broadband monopole antenna is vertically polarized, has a low angle radiation pattern and is used for short range circuits by ground wave and medium to long range circuits by sky wave.

            The antenna is broadband, omnidirectional and conical.

            The broadband frequency capability does not require tuning.

            The radiation pattern in the azimuth plane is essentially omnidirectional, while the elevation pattern varies with frequency.

            The support structure is a guyed mast supported on a base insulator.

            The radiator comprises a biconical cage of wire.

            Monopole antennas require a radial ground screen for specified performance. The ground screen consists of wire conductors laid out radially from the tower base and terminated at the outer end.
