Antenna transfer assembly with jam preventing inserts

摘要

A flexible antenna cable is deployed or retrieved by movement along a helical path through an enclosure passage formed between internal surfaces of an assembly within which a plurality of cable pulleys are disposed in contact with the cable for exercising drive control over cable movement. A plurality of solid inserts shaped to occupy spaces between the pulleys within the helical passage, preclude buckling of the antenna cable during deployment and thereby prevent jamming.
