ABSTRACT:
A deployable and retractable mast which can be rotated while deployed, using only one drive means for all three functions. Flexible longerons carry followers which pass through guides in a storage cannister for transition between a coiled retracted condition and an extended deployed condition. The followers pass through a gate opening, past a gate, and when the mast is rotated, the gates enable or prevent followers from taking the longerons into the retracted condition, and entitles rotation of the mast when retraction is disabled.
