Installation

suggested installations. For best performance, the antenna
should be installed with the radiating elements in a horizon-
tal ("Fiat Top") configuration, and as high as possible.
the directions of maximum radiation and
are at right angles to the radiating elements, and
this should be considered when planning installation.
this radiation pattem is based on an ideal anten-
