About this episode
Shielded network cable costs more to buy, more to install, and more to maintain — and most buildings never need a single run of it. This episode covers where shielding is actually required, what a correct shielded installation involves, and why we recommend a certified installer for the rare runs that qualify.
The Frugal Admin position: measure before shielding, prefer fiber where both endpoints have fiber interfaces, and spend your money on the parts of the network you use every day.
