How can a ferrite clamp be called a CMAD Common Mode Absorption Device? It
reduces EM radiation 
by reducing the current through the "antenna", not by absorbing RF. It
could, however, be called a CMAD Common Mode Attenuation Device.

You mean me?  And do you mean before I make a name for the device or
before I make a DIY device itself? I don't plan to do that at present,
but you never know.

The discussion in the UK committee leads me to think that the 'MAD' part
is apt. (;-)
