Abstract
A power antenna drive cable seal has a dynamic response to cable winding direction that allows the cable to slide through freely on the up stroke, when it is under compression, but which vigorously scrapes the cable on the down strike, when it is under tension. The seal is a resilient, bellows shaped unit with a flared throat that changes from a divergent, cable passing shape to a convergent, cable grabbing shape. the shape change is caused by the axial force of the cable changing direction.
