Why would you need to do that?

Re: by winding es unwinding the jacket
gets a workout, eventully water will start
entering cracks, degrading the inner surface
of the shield es intering the foam if used
(a good reason NOT to use foam cable here)
and increasing the attinuation of this cable.
This makes an antenna problem (read: loose
clamps on the ends of the straps) here, harder
to detect.
You can reuse the connectors (once you learn how)
so it only costs you 10' of RG8-U (or RG-213/214-U)
to remove this `weak point' from the most
important part of the H.F. station. This should
be done at the annual tower/antenna inspection
time.
p.s. any water that has entered into these connectors
will also befound and removed.
