[TowerTalk] broken balun wires

[Steve Katz]

I don't even like using "wires" for high vibration installations; even
if they're stranded, they'll eventually break.

This is more a job for woven braid material with thousands of strands;
either that, or mounting the balun directly to the element connections
using flat aluminum or copper strap, and mechanically bonding it all so
they all vibrate together...

:::: You were not crimping the lug?
I would crimp it AND solder it.
