[TowerTalk] RG6 flooded cable issue

[Steve Maki]

As a reference point, I have the DXE 8 circle, and had occasion recently 
to replace the center relay box. All of the connectors looked like the 
day I installed it a few years ago. I used the DXE supplied flooded 
cable...but like I said, I've never seen dielectric grow. Did the foil 
shield grow with the dielectric?
