In recent years, the guy wires on my tower have become what may be dangerously
rusty, and I plan to re-guy. The tower is 127' tall with four guy levels, one
every 30 feet.
The rust pattern is very interesting. The guys at the top two levels are far
more rusty than at the bottom two, even though all the guy cable came from the
same roll. I could probably get by with the original bottom sets of guys for
many more years, but the top two definitely need replacing, sooner not later.
The only reason I can possibly figure for the differences in the rust pattern
is that the slope of the upper guys is much steeper, and water would tend to
run down the the wire and stay in contact with the metal for longer, whereas
the lower guys are closer to horizontal, enough that water would tend to drip
off instead of running down the wire all the way to the end. The amount of rust
is nearly the same on the top set and next one down, and nearly the same for
the bottom set and next one up, but the difference between the second and third
guy level is tremendous.
