A well-made, double-shielded cable
What about a network cable?
I used it to run the network in my ducts, so on that subject :
- Having cut it up, I can attest that the shielding is both overall and on each pair.
- The cable is covered with a material that made it fairly easy to pass through the technical duct of already closed walls as a replacement for a TV coaxial cable.
It does the job perfectly.
