Abstract: An approximately circular, flexible apron is secured to a pole passing through its center. Sand, rocks or other ballast material is placed upon the apron, thus allowing it to serve as an anchor. The apron may include battens to maintain the extended surface upon which ballast is placed. The apron may also be attached to a radial array of support members that are connected to a slide collar that can be locked to the pole. Through the adjustment of the slide collar, the apron can be shaped to provide a basket shape to hold ballast, or the apron can be disposed as a flat surface upon the ground allowing the support members to contribute lateral support to the pole.
