Oh, hold on guys!:) The 15m array is still up and running! Good way to get
those rumors going:) I did lose another 45m rotating tower 2-3 years ago though
due to the turnbuckle failure. The tower went back up last autumn with new
antennas. It was a painful lesson and certainly I am using safety wires on all
my turnbuckles now!
I did learn about the saddling of the dead horse thing and have fixed the wire
rope clips. The only thing that I am probably not doing right is the distance
between wire rope clips on the wire. Given I had quite long ends of the wire
left over I left also half a meter or more between 4 wire rope clips (the first
one right after the thimble).
Is it and why is it crucial to keep the wire rope clip close to each other on
the wire (2" or so)?

I’m sorry to learn that Tonno lost his tower and incredible 8 x 5 L array.
It’s terrible that it happened when it was so easily preventable!
For each of my tower guys, I always cut them so that each guy has an extra 5 ‘
– 10’ of 1/4” EHS left over, and then, rather than cut off the excess, I simply
run the extra through both ends of all the turnbuckles and then through all the
bolts on the equalizer plate.
It doesn’t make any sense to allow the turnbuckles to potentially turn and undo
themselves and thereby jeopardize the tower. I even use ice clips for the same
reason on every guy wire – to potentially prevent yet another mode of failure –
especially one that is so prevalent at my qth.

The wire rope clips are also completely misplaced on the ES5TV guys.
They should be about 2" apart and first one tight to the thimble. I can't tell
from the video if he saddled a dead horse. l'd also bet there was no torque
wrench used. It looks like pretty skimpy wire and turnbuckles for that load
even with 5 levels of guys. Sad. So easy to do right.
A figure eight of EHS thru the eyes/jaws and center not only prevents rotation
but covers several turnbuckle failure modes as well (done on my tower). If the
thimble and anchor shackle are large enough to thread the EHS thru then with
any turnbuckle failure the guy is still attached.
