I asked a friend who has had a EF-420/240 up for probably 20
years. His reply:"I have not changed the wire. Should I need to in the future,
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 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
