Well, if the objective is to keep all interconnected equipment at the 
same potential, we want connections some small fraction of a wavelength 

Lead inductance is the problem; EMC Engineer and author Glen Dash 
(WB9CLJ -- may not be active, no antennas seen on satellite view) used 
to say "Ground isn't ground the world around"; IIRC, he once suggested 
using a really big sheet of metal with substantial capacitance as a low 
inductance RF ground.
