M&P: BroadPro50 double jacket

This cable has a solid inner conductor with 2,7 mm diameter, but that is not the gist. The trick here is the outer jacket. It is double layered: the outer layer is made of PVC. The inner layer consist of red polyethylene. Though, watertight and red. It is red so that you can see damages after 'misuse' at first glance. If only the outer layer is damaged: self-amalgamating duct tape or heat shrink sleeve with glue on the inside applied at the breach, done! And if the inner layer is damaged too? Well, additionally copper braid and copper foil are waxed with paraffin-like grease, which also improves the cable's flexibility, too.
