9. The antenna mount of claim 1 , further including at least one adjustable connection hole in the mounting surface aligned with a bolt hole of the base portion; the adjustable connection hole and the bolt hole coupled by a third fastener.
10. An antenna mount, comprising:
a first end portion and a third end portion;
the first end portion having a projecting second cam mount and a pivot hole;
the third end portion having a second cam slot and an angular slot having a radius of curvature generally centered upon the second cam slot;
the first end portion and the third end portion adapted to mate whereby the second cam mount projects through the second cam slot and an angular slot fastener couples the first end portion and the third end portion together via the pivot hole and the angular slot; and
a second cam with a second eccentric mounting hole mounted upon the second cam mount;
the second cam rotatable about the second cam mount pivoting the third end portion about the pivot hole as a contact edge of the second cam abuts at least one second cam guide(s) of the third end portion.
11. The antenna mount of claim 10 , wherein the first end portion is normal to a base portion between the first end portion and a second end portion also normal to the base portion;
the third end portion is normal to a central portion between the third end portion and a forth end portion also normal to the central portion;
the second end portion and the fourth end portion coupled along a first horizontal axis passing through the second cam mount;
the second end portion and the forth end portion also coupled along a second horizontal axis passing through the pivot hole; the first horizontal axis and the second horizontal axis both normal to the first end portion.
12. The antenna mount of claim 11 , wherein the base portion has a first cam slot and a pivot bolt hole adapted to align with a mounting surface of a primary bracket having a projecting first cam mount and a pivot connection hole adapted to align with the first cam slot and the pivot bolt hole, respectively;
a first fastener coupling the base bracket to the primary bracket between the pivot connection hole and the pivot bolt hole, the first cam mount projecting through the first cam slot; and
a first cam with a first eccentric mounting hole mounted upon the first cam mount;
the first cam rotatable about the first cam mount pivoting the base bracket about the pivot connection hole as a contact edge of the first cam abuts at least one first cam guide(s) of the base bracket.
