The same caveat should be applied to 9913. Since the inner conductor of
9913 is a solid wire, it shouldn't be used in an application where it'll be
moved; i.e. rotator loop or on crank-up. Over time, it will crack and break.
There are some new 9913 clones that have a multi-strand inner conductor that
will take the movement with no problem.
The only way you could use hardline on a crank-up tower is if you never
lower it once it's extended.
