Patent ID: 8910432

Claim:
A tower structure, comprising: a base plate adapted to be coupled to a stationary base plate; a flange hingedly coupled to the base plate, the base plate and the flange being movable relative to each other in a first rotational axis; an intermediate structure coupled to the flange; and a mast structure coupled to the intermediate structure at a fulcrum providing movement of the mast structure in a second rotational axis relative to the intermediate structure, wherein: the base plate has a first plurality of through-holes and a second plurality of through-holes, wherein each of the second plurality of through-holes are disposed in a position between each of the through-holes of the first plurality of through-holes, and the flange has a third plurality of through-holes that substantially align with the second plurality of through-holes in the base plate and a fourth plurality of through-holes each having a dimension greater than a dimension of each of the third plurality of through-holes and disposed in a position to substantially align with the first plurality of through-holes in the base plate.
