Title: PRE-TUNED HYBRID LOGARITHMIC YAGI ANTENNA SYSTEM
Abstract:
A hybrid logarithmic yagi antenna system (10) characterized by the absence of a balum or other conventional log periodic yagi antenna system balanced feed and impedance matching means. The reflector (12) is configured as a supporting conductive tray (52) which provides a rugged mounting for mounting the antenna system (10), at its reflector (12) end, to a support structure such as a building. The antenna has a log periodic dipole array (14), a director section (16), and focusing element (18), and where the director section has a plurality of director elements (20).
