    Abstract: An antenna mast and method of using it relate to a retractable mast having a retractable mast having a plurality of tubular telescoping sections to enable the mast to move between a fully retracted storage position and a fully extended use position. Each section is equipped with a thermoplastic bearing to facility rapid deployment. Pairs of diametrically opposed pulley mechanisms are mounted on opposite sides of each one of the sections, and the pairs of pulleys are angularly displaced from section to section for facilitating the structural stability of the deployed mast.
