As per the manual.

Only substituted the tiny rivets that hold the elements together for
larger ones.  No problems here.

Installed as per the manual.

The failed rivets in question were installed by the factory.

Ask Tom, the factory installed them.

Again, ask Tom.

Ask the factory, they installed them.

Trust me, I do.  I'm tired running up and down the tower with this thing
to fix things that were factory installed.

And so they should.  They used the wrong rivets (as admitted by them).
They created the problem, they should fix it.

>regardless of what the real "root cause" of the problem was.  

We know what the root cause of the problem was.  The factory installed
the wrong rivets.

They received approx $1000 for a product which failed due to their
mistake.  Of course they should me made to behave responsibly.  If you
bought a car from Ford and it failed due to their mistake, you'd expect
them to fix it, wouldn't you?

That is exactly what has been tried, but Tom ignores any correspondence.
Have you any better suggestions?

At the same location there are eight other totally homebrew yagis which
have had ZERO failures of any kind (and most have been installed
longer).  One of these, a 4el 20M yagi on a 40ft boom is only about 6ft
below the 40M failure so it gets similar winds.  Why should the F12 have
so many failures when all the homebrew ones have none?
