  • Low profile bi-directional antenna
    Patent number: 6037912
    Abstract: A low profile bi-directional antenna is provided for mounting directly to a metal structure, or some other conductive or semi-conductive surface. The antenna includes an insulating antenna tray, a conductive ground plane mounted to a surface of the antenna tray, first and second radiating elements extending from the ground plane, and a radome covering the radiating elements and fastened to the insulating antenna tray. First and second reflector elements are mounted to the surface of the antenna tray on the lateral sides of the ground plane. The reflectors are electrically connected to the ground plane. The radiating elements are supported above and to the lateral sides of the ground plane and reflector elements by support members mounted at acute angles to the ground plane. An RF connector is provided for coupling RF signals to and from the first and second radiating elements.

  • Pre-tuned hybrid logarithmic yagi antenna system
    Patent number: 5898410
    Abstract: A hybrid logarithmic yagi antenna system characterized by the absence of a balun or other conventional log periodic yagi antenna system balanced feed and impedance matching element. The reflector element is configured as a supporting conductive tray which provides a rugged mounting mechanism for mounting the antenna system, at its reflector end, to a support structure such as a building.

  • Adjustable mobile antenna mount
    Patent number: 5402135
    Abstract: A mobile communication antenna adjustably mounted to a base at desired angular orientations. A decorative cover snap locks to the base to cover the antenna base structure. The cover includes a small opening through which a portion of an articulating arm extends to provide a wide range of angle adjustments of the antenna within the opening in the cover. The articulating arm provides an offset between the antenna axis and the axis of pivotal movement.

  • Unitary cellular antenna system
    Patent number: 5262795
    Abstract: The unitary cellular telephone antenna includes a junction box to which is mounted both the antenna element, preferably a 5/8 wavelength antenna, and two 1/4 wavelength downwardly oriented radials to establish the antenna's ground plane. Electrical elements are included within the junction box to match the impedance of the antenna system to the cellular telephone transceiver and to maximize the radiated signal.
