ABSTRACT:
A readily assembled self-supporting structure for carrying an antenna and associated electronics apparatus includes a tripod base having support means for pivotably supporting a top mast on which the antenna and associated apparatus are mounted. Pivotably joined with the support means, a mast engaging member is adapted to swing in a predetermined direction to either raise or lower the mast. A heavy battery pack used to power the apparatus is pendulously suspended from the member below the support means and stabilizes the structure against wind forces without requiring ground anchors. In addition, the battery pack acting about the pivot erects the top mast in a perpendicular attitude irrespective of the slope of the antenna site. The structure is held rigid by means of three guys between the top of the mast and the feet of the tripod. One of the guys may be removed to allow the mast to swing when the battery is raised and the tripod legs are prevented from splaying at ground level by a continuous loop of wire rope passing through support pads on which the base rests.
