                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 --------From: Bryan Swadener via TowerTalk <towertalk at contesting.com> Date: 12/21/19  11:37 AM  (GMT-06:00) To: towertalk at contesting.com Subject: Re: [TowerTalk] Force12 rebuild  I'm using nickel-copper wire rope on the 40m linear loaded elements of my F12 C-4XL.

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  ______________________________________________________________________________________________TowerTalk mailing listTowerTalk at contesting.comhttp://lists.contesting.com/mailman/listinfo/towertalk
