Thanks, I will pass this along to my friend.
Hmmm.... you ask why the concern about shielding on my part? - I guess I was remembering "AC" 60Hz "Hum" getting into speaker wires somewhere in my past.

My mistake on the coax number.
On the cable itself and everywhere in my notes it is 9248,
but somehow in my post I put 9254.
I guess my brain likes 54 better than 48,
maybe something to do with my birthday...
As you get older, these sorts of things happen.
Oh well what's six years when it comes to coax numbering
The coax is labeled all along it's length:
Belden - 9248 Duofoil-Braid 75 Ohm
AWM style 1354 VW-1
It is solid core, with Al foil wrapped along with the braid layer.
