[RFI] ISOBAR

[Pete Smith N4ZR]

I use a piece of 3/4 inch copper pipe running along the rear of my desk 
as a ground bus.  All of my radios, computers etc. are fed off a single 
branch, and each is grounded to the pipe by a short, direct copper 
wire.  The copper pipe is connected to my aluminum entry panel, and from 
there #2 solid copper goes to my power-line input ground.  
Unfortunately, that wire has to be around 40 feet long, so I know it's 
not ideal. Not all of us can have purpose-built shacks with perimeter 
grounds and copper strap galore.
