[RFI] DFing intermittent connection

Jim, 


It was a terrible idea and its still a terrible idea. 
RG-8 uses braid not stranded wire. Braid is 
an inappropriate choice

Mostly just a convenient source of stranded wire. Possibly a bit better with braid.

Hi Jim, 


The wisdom of using RG-8 for this application is not apparent to 
me. Why not use an appropriate solid or stranded wire with lugs 
on each end?

I had envisioned RG-8 with the braid and center connected together, with appropriate lugs on each end to attach to a clamp or tower bolt, and weatherproofing it to keep it all dry.

Jim, 


Please ignore Scott's advice, it will cause tower corrosion and quickly fail

Or just use the braid from some RG8 and a couple hose clamps.
