Radio. Every wire is an antenna. Do you understand how radio works? Transformers? Same thing.There are NOT entirely the same thing…
The majority of antennas are primarily designed as E-Field devices, (at least if we ignore loop antennas for tracking bats and fish).
The majority of ground loop problems are predominantly due to magnetic fields and coupling of those fields.
In fact, in a toroidal transformer there are no/little external magnetic fields… So it is clearly not an antenna
And we have not as, of yet been presented with a clear picture of what frequency(ies) the noise is operating at, we don’t really have a lot to go on in any objective sense.
It is sounds like everything/everywhere is a source and there is a Yoda like “Disturbance in the Force” that is picked up be sentient equipment.
I am not saying the stuff doesn’t work, but when Bryson and Pass say don’t waste money on them, and there is no before and after showing some goodness is happening… then it looks it can be higher on magic, BS, nano particles (etc), and somewhat light on provable facts.
If the OP wants a new cord, then “more power to him”. At least they look nice.
The fact that many people I know swear by them is perplexing to me, but I have not had access to try any for a free demo… So I have no subjective opinion on their effectiveness..
