My TH7, assembled according to the manual with ropes and end caps, was
up for almost 30 years, with no failures. I do wish I had noticed before
I put it up that a few of the parts weren't stainless.

I believe that the rope in the elements, specifically the element tips, is
particular to the Hy-Gain yagis, at least the 20, 15, and 10 meter designs. I
have seen a Hy-Gain yagi, a 5 element 15 meter yagi, with most of its element
tips broken off by regularly occurring, but not huge, winds. The yagi was built
without the rope in the element tips that is shown in the manual for the
antenna.
I replaced the element tips in 1992, with the rope in the tips per the
instructions in the manual, and did not have any element tips break off during
the next 17 years of service at the same location.
Just sharing my experience.
