  • Patent number: 4878062
    Abstract: A low profile, low drag, broad-banded antenna system includes four substantially identical antenna elements in intimate contact with a hemisphere of high dielectric constant material. The antenna elements are equally spaced from each other around the hemisphere and are connected to a power divider circuit for reception of incoming signals from a global position satellite having circular polarization. A dielectric phase equalizing member of variable thickness surrounds the antennas in intimate contact therewith for improving the axial ratio particularly at low angles of radiation. The dielectric phase equalizing member is also formed from a high dielectric constant material. A radome of a radio transparent material covers the assembly to provide an aerodynamic configuration and to protect the antenna from the weather. The antenna has a gain from approximately -2.5 dBic at 10.degree. above the horizon to approximately +3 dBic at 30.degree. above the horizon.

  • Patent number: 4506311
    Abstract: A lightning diverter strip is provided with button elements in the form of diamond-shaped conducting segments which arranged longitudinally on the strip in spaced-apart relation, with the sharp corners of each of the button conductive elements in longitudinal alignment with each other and with the opposite corners presented along the edges of the strip. The spacings of the conductive elements at the corners may be varied so that some of the elements are spaced more closely together than are other ones of the elements, to provide a lightning diverter strip having a lower break-down voltage potential.

  • Patent number: 4486805
    Abstract: An improved arc gap structure for a lightning arrester comprises first and second annular electrodes concentrically arranged relative to one another. The first electrode has a generally cylindrical inner surface which tapers to a smaller diameter toward one end. The second electrode has a generally cylindrical outer surface which is sized to be spaced apart from the inner surface of the first electrode when received therein. The electrodes are axially displaced relative to one another such that the spacing between the upper corner of the second electrode and the tapered portion of the first electrode define the ignition arc gap for the lightning arrester. The second electrode is preferably axially adjustable relative to the first electrode to select a desired arc over voltage for the lightning arrester.

  • Patent number: 4262321
    Abstract: An aircraft static discharger and mounting structure therefor is disclosed formed of non-metallic conductive material, such as carbon filled nylon, for mounting an aircraft static discharger onto a graphite and/or boron composite aircraft skin. The discharger includes a mounting structure formed as a sub-base having a lower surface provided with downwardly extending conical projections terminating in points which engage the underlying graphite composite surface and form electrical contact therewith, providing for the mounting of the sub-base to the composite surface by conventional non-conductive epoxy. A surface conductive to lightning currents is provided by bonding powdered aluminum to the outer surfaces of the discharger base and the sub-base which, together form a lightning diverter strip formed on the discharger, transfer lightning currents over the surface of the base and sub-base to the underlying aircraft structure.
