1. A pivot bracket assembly, comprising:

  • a pair of disks, each disk having a center, a diameter, an outer perimeter, and generally circular inner and outer faces;

    each of said disks having a generally circular hole therethrough extending between said inner and outer faces of said disk, said hole of each disk being positioned at said center of said disk;

    said inner faces of said disks being positioned adjacent each other such that said inner faces of said disks abut each other, said holes of said disks being coaxial;

    a threaded fastener having a head portion and a threaded portion, said threaded portion being extended through said holes of said disks such that said head portion of said threaded fastener is positioned adjacent said outer surface of one of said disks and said threaded portion extends outwardly from said outer face of the other of said disks, said threaded fastener permitting rotating of said disks with respect to each other about the axis through said centers of said disks;

    a nut being threaded on said threaded portion of said threaded fastener to hold said disks together between said nut and said head portion of said threaded fastener, wherein a washer is disposed around said threaded portion of said fastener between said nut and said outer surface of said other disk;

    said inner face of each of said disks having a plurality of teeth ridges thereon, each of said teeth ridges having a length extending radially outwards between said center and said outer perimeter of said disk;

    said teeth ridges of one of said disks meshing with said teeth ridges of the other of said disks when said inner faces of said disks abut each other, said teeth ridges being for providing additional friction against rotation of said disks with respect to each other once the nut is tightened on the threaded fastener;

    each of said disks having a circular shape such that said perimeter of one of said disks is aligned with said perimeter of the other disk for preventing foreign objects from becoming pinched between said disks when said disks are rotated relative to one another;

    said outer surface of each of said disks having an angle arm outwardly extending therefrom, said angle arm being extended substantially perpendicular to said outer surface of said disk, said angle arm being positioned adjacent said outer perimeter of said disk;

    said angle arm of each of said disks lying in a plane generally perpendicular to the diameter of said disk;

    each of said angle arms having a generally circular hole therethrough, said hole of said angle arm of one of said disks being threaded;

    a first securing assembly mounted on a first one of the angle arms, the first securing assembly including a threaded rod having opposite end portions, a first end portion of the threaded rod extending through the hole in the first angle arm, and a waveguide hanger mounted on a second end portion of the threaded rod, the coaxial cable hanger comprising a central portion and a pair of oppositely extending arms mounted on the central portion, each of the arms having a free end with a retaining tab mounted thereon and extending substantially parallel to the threaded rod; and

    a second securing assembly mounted on a second one of the angle arms, the second securing assembly including an angle adapter for attachment to a tower structure, the angle adapter having a U-shaped member with legs extending away from the second angle arm and defining a gap therebetween, a threaded bolt extending through one of the legs into the gap between the legs for selectively engaging a structure extending through the gap.
