I hadn't ever heard of guy anchors on ham radio towers failing because of
corrosion I'm wondering if it's something all of us need to worry about -
anyone with firsthand experience?

> HELPFUL ADVICE ON GUY ANCHOR INSPECTIONS (CGC #570)
>
> Over the years there have been numerous instances of towers
>falling due to guy anchor failure, with guy wires hanging on to
>as little as 1/4" of remaining shaft before failure.
>
> As a Tower Safety and Rescue trainer for our company, I have
>taken trainees to a guyed tower to see the "point of daylight."
>This is where the guy anchor meets the dirt, and is the most
>likely place to reveal corrosion just below the surface, as shown
>in the diagram of CGC #570. Dig down about 6-12 inches and you
>may likely find the beginnings of corrosion. This inspection
>should be performed regularly if you own a guyed tower.
>
> The best way to prevent or delay the corrosion process is
>through the use of a "Sacrificial Anode" - or Cathodic Protection.
>You can see the process of corrosion and how it can be prevented
