Abstract:
1. A portable base for supporting an upstanding mast comprising: a plurality of metal panels including a top panel, a bottom panel and a plurality of side panels shaped and arranged to form a container with inside surfaces of the metal panels enclosing a hollow interior; the top panel having a sleeve attached thereto and extending therefrom generally at right angles to a plane of the top panel downwardly into the hollow interior so that the sleeve extends from the top panel through the hollow interior to the bottom panel; the sleeve having an open mouth of the sleeve exposed at the top panel arranged to receive and support the mast to hold the mast longitudinally along the sleeve; the hollow interior being filled with a set solid material which is set from a settable material filled into the hollow interior so that the set solid material substantially fills the hollow interior and surrounds the sleeve; the set solid material being in intimate contact with an outer surface of the sleeve and at least part of the inside surfaces of the top and bottom panels so that the sleeve is held in place by forces contributed both by the set solid material and the top and bottom panels; wherein there are provided reinforcing bars mounted inside the container and extending through the set solid material.
