[TowerTalk] Coax ground braid

[Bob Ad5vj]

I needed to run a flat ground braid for my shack for a common ground. 

Instead of buying one I have ripped one of my RG-11 coax stubbs planning to use the shield from it for the flat copper braid.

In doing so, after removing the outer jacket I see places where the copper is black in some areas. Some places as much as a foot long.

1. Will this hurt the conductivity as a ground braid assuning I clean it up where I make contact from the equipment?

2. Has anyone seen this before?

3. Does this mean I need to changeout all my 3yr old coax outside which came off the same roll at the same time?

tnx Bob AD5VJ
