Plugs and Wires

if the antenna length is a multiple of half the signal wavelength. So with the various lengths of plug wires, there is an enormous chance the radiated noise will be undesirable at a huge number of frequencies..

Actually it's much worse than that, and I don't even understand the math, LOL

1/4 wave is what makes a radiator in a situation such as a plug wire, and it doesn't even have to be 1/4 wave. All it has to be is long enough that the impedance is great enough to allow RF voltage to climb at the far end of the radiator enough to cause the "damage." Since we are talking about such short distances, IE, LOL we are not Marconi in the "spark" days trying to hear the Titanic, LOL

This is allegedly an authentic photo of the Titanic's radio room



The Olympic's radio room, Titanic's sister ship is often pictured, but it is claimed that Titanic's radio room was actually quite different in layout

From the James Cameron movie. Isn't this a warm, cozy place? Hell, THIS could never sink
