I was not aware that Tonno's 15m system fell down. This is very sad news. I
suspect that there is more to the failure than just a missing safety wire.
The tower looks as least as big as Rohn 65g and probably even stronger. It
must have been fun designing, building and operating a 15m antenna system
like that. He was even able to have a QSO with himself via moonbounce.

Man! 70 meter (227 ft) tower with 8 5L 15 meter monobanders. An installation
like that with no safety wires on the turnbuckles. No matter the planning,
something always gets missed. (I retired as a project manager at the
corporate level for a large multinational corporation) I don't know what
that tower was, (looks larger than 55G) but it makes my 45G look like a toy.
The diagonal braces appear to be rerod. I assume they are the weldable
variety. That tower was strong. Looking at the lift, there was a lot of
tower beyond the lift point and no visible sag!
Impressive video!

If my gray matter recalls, ES5TV lost his fantastic 8 - 5 element H

ARRAY because he did not use safety wires on the turnbuckles and lost the
installation ! https://www.youtube.com/watch?v=Z9fDlbIFhMs&t=7s
