Tom I'm not questioning your experience or testing, but what are the
manufacturers of duplexers missing?  They seem to think that double
shielded coax on their harnesses is of some value.  I would think it if
made no difference, they would use less expensive components.

I suspect it does make a measureable difference, and while it may be
functional with 95% braided coax, their must be a reason they don't use
it for the harness.
