Has anyone done any experiments with corrugated steel and wiring to see what the effect is on low frequency noise, as a way to shield a cable other then twisted pair for that frequency range?
I only have aluminum spiral, and it seems you need a helmholtz setup to test this, but has anyone seen the results of this type of shielding?
not a bad project to make the tester either.. I just want to see if there is a reason not to do so more then if there is a reason to do so
