replaced my guy wires after a strike. US Towers recommends changing
frequently, regardless of lightning, but very few people do it.
For one they typically can't - it's not an easy job.
Also, the 3-year cable replacement recommended by UST is a weasel
clause. That is, if you have some semi-fatal problem and you didn't replace
cables, they can weasel out of any responsibility.
In typical usage, I've never seen crank-up cables that actually should
have been replaced - even in crank-ups 20 years old and older.
