Patent ID: 7015872

Claim:
In an antenna installation having a tower including a mast supported adjacent its upper end and in turn being supported by a first hinge means for pivotal movement about a first horizontal axis between a generally horizontally disposed lowered and vertically upstanding use positions, and an antenna including a boom mounted on an mast and a plurality of antenna elements mounted on said boom to lie within a plane disposed generally normal to said mast when in said upstanding use position, the improvement comprising in combination: a second hinge means for mounting said boom for pivotal movement relative to said mast about a second horizontal axis disposed generally parallel to said first horizontal axis, said boom being disposed adjacent a side of said mast arranged to face downwardly when said mast is disposed in said lowered position, and said boom tending to swing about said second axis in a direction away from said mast under the influence of gravity to position said plane at an inclined angle relative to said mast when in said lowered position.
