Portable support mast
A hub, an extensible vertical member pivotally attached to the hub for movement between a stowed position and an erect position, and at least three extensible horizontal members each pivotally attached to the hub for movement between a stowed position and an erect position. The vertical member and the horizontal members are each extensible such that a ratio of the extensible length of the vertical member to the extensible length of the horizontal members is adjustable for required stability in high wind applications.
