Even if the #6 wire only connects other gnd rods to
the central ground, and is buried bare? Having a hard
time seeing the inductance problem, Running a two foot
wide strip of flat copper is a nice idea, but when you
eventually connect to your equipment, you still have a
conductor only as wide as the connection bolt. Should
I build my operating table out of a solid cast copper
block extending directly ten feet into the ground
below my shack, with a few hundred strips of flat
copper running in all directions from that? Bolt the
entire chassis of each radio to it and call it good?
Or would a faraday shield be of added benefit? Hi Hi
