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.
