I would use #14 copperweld as I think this wire would be as strong as the 
aluminumweld used by F12. Might be good, however, to check on mechanical specs 
of the copper clad steel wire.This loading wire also acts as truss wires to 
physically support the elements."Climate is southern WI so plenty of snow, ice, 
and temps from below 0 to 100 degrees.73,Gary K9GS-------- Original message

[TowerTalk] Force12 rebuild  I'm using nickel-copper wire rope on the 40m 
linear loaded elements of my F12 C-4XL. McMaster-Carr has 7x7-strand 1/16" 
diameter for $1.24/ft (#3453T32).Bryan WA7PRC:

[TowerTalk] Force12 rebuildHi all,I'm rebuilding my Force12 40m yagi. What 
would you recommend as replacementfor the alumoweld linear loading wires? Some 
of these wires have snapped inthe past due to years of vibration.Note: as part 
of the rebuild I am adding truss supports for the 3 elementsin order to remove 
the stress on the linear loading wires.73,Kris N5KM
