[TowerTalk] Force12 rebuild

[Robert Harmon]

Kris,

I have a JK 403 40M yagi.  It does not use the linear loading wires like the older Force 12 did.  It uses a small shunt coil at the antenna feed points.  
How about using stainless steel rod ?
I don't know what the diameter of the wires are but I just looked at an on line company that has 1/4" dia, 316 SS rod it up to 144" long.
SS should outlast the alumaweld.
