ABSTRACT:
An antenna mast is constructed from telescoped tubes which are extended for deployment by hydraulic or pneumatic pressure, the tubes when extended, are latched to each other internally, permitting depressurization. A set of unlatch cones becomes sequentially effective to unlatch the latches, beginning from the top to stepwise telescope the tubes into each other. Spring biased latches are mounted on an insert in the bottom of tubes; the unlatch cones, except the highest ones, extend from the bottom of the inserts.
