A ballasted support base is disclosed which may be used to support a large variety of structures and objects. In the preferred embodiment, three equal arc-shaped tanks are fastened together to form a disc-shaped base. When empty, the tanks may be easily transported and they may be stacked to occupy minimum space. When the tanks are fastened together, a flange is used to support a center plate which in turn supports a pole. A plurality of diagonal supports are attached to the pole and the periphery of the base. Each tank comprises a cap for preventing liquid from evaporating and a recess is provided on each tank to allow the tanks to be stacked without interference from the cap. Each tank may also comprise stiffeners for withstanding compressive loads and an adjustment plate may be used to adjust the angular position of the pole.

[ What is claimed is:] [1.] A liquid ballasted support base for supporting an antenna from a surface, comprising:(A) a plurality of similarly shaped ballast tanks, the tanks having a substantially uniform height with a constant vertical thickness when resting on the surface and being shaped to allow the tanks to be nested in an orderly collection during transportation and storage, each tank comprising:(a) a single-piece tank wall defining an internal cavity, the tank wall providing a substantially leak-proof barrier, wherein a liquid may be held in the internal cavity, the tank wall being adapted to support itself when the internal cavity is not full of liquid, the tank wall having at least one support portion, the support portion being adapted to abut and support a support portion of an adjacent tank when the tank is attached to the adjacent tank;(b) an opening in the tank wall, the opening being adapted to allow liquid to be added to the internal cavity; and(c) a cap removably attachable to the opening, the cap being adapted to close the opening,wherein the plurality of tanks may be attached together in a side-by-side relationship on the surface, wherein each tank rests on the surface and the support portions of each tank abut and support the support portion of at least one neighboring tank;(B) a mast attached to at least one of the tanks, the mast being adapted to support the antenna; and(C) a support structure attached to at least one of the tanks and to the mast, the support structure being adapted to support the mast, wherein the mast may be positioned to support the antenna above the surface and the tanks provide a stabilizing force.
