Abstract: An improved portable support for insertion into the ground is provided that more efficiently penetrates the ground, increases the depth to which the support may be inserted into the ground, improves the strength and support of the invention, decreases the amount of earth that must be displaced during insertion of the invention into the ground, and stabilizes the invention by allowing earth to flow up into the support during insertion of the support into the ground. The portable support includes a tube with an open end and an open coil. A first end of the coil is coupled to the open end of the tube, and a second end of the coil is configured for insertion into the ground. The coil is shaped so that a diameter of the first end of the coil is greater than a diameter of the second end of the coil.
