Abstract: A telescoping mast for deploying, retracting and securing a payload of equipment. The mast is formulated using advantaged geometry and comprises interlocking support legs and relatively lightweight skins mounted between the support legs as its base structure. In addition, some embodiments of the disclosed apparatus provide a secure channel through the mast for cables necessary for the operation of equipment mounted in a payload. Still further, some embodiments of the disclosed apparatus provide a wire rope and pulley system to raise and lower the mast and include structural flexibility to enable the telescoping mast to be used at various intermediate heights in between full extension and fully retracted.
