My $0.02 worth - I would go to the nearest electrical supply store and
purchase 13 ga copper stranded wire with a plastic coating and a small
piece
of either plastic or rubber tubing and slide the antenna wire into the
tubing only enough to where you need to run the whole assy thru the
pulley.
The 13 ga wire is stronger than the RS wire and the outside covering
should
withstand the abrasiveness of the pulley!

Thanks Howard. Does the plastic coating affect the signal at all?

I don't know where the 13 wire comes from , but the most common will be
either 12 or 14 in the US. Anyway the plastic or any other coating will
have no noticable effect on the antenna as far as the signal. It will
have a slight shortning effect on the length, but usually 20 meters or
higher is where that shows up. The higher the frequency the more the
effect shows up. Up to 10 meters, the standard formulars are still close
enough for a starthing point.

13 ga copper stranded wire is also very common here in the USA... I am
running 540 ft of it as a longwire (stealth Antenna) from 160m to 70cm -
driving it with an Icom AH4 tuner... works like a champ... No the outer
jacket should have no effect on your signal, you might have to trim the
lengths of the dipole since you will be using a larger gauge wire...
