Simple solution.  Wrap the entire station in copper mesh.  Tie it to the 
radio ground.  Now you and it are at the same potential.

Is being done with Very High Voltage lines by bonding the helicopter to 
the main voltage lines.

It works fine - JUST as long as every one does everything "perfectly".

Same half-baked philosophy given by folks that counter that the green 
wire and white neutral are bonded to SAME place in the main panel.  
(They ARE BTW!)

This is all trying to confuse the FACTS and the REALITIES!

One ground rod, OR an entire ground grid with a DOZEN ground rods will 
NOT keep RF out of the shack!

Why?  Because the end of the feed-line or coax is attached to the 
RADIO!  In turn the RADIO is Grounded through its power cord to the 
HOUSE GROUND and the ENTIRE panel distribution system.

You can do the whole ground grid system and STILL get RF burns!

All the JUNK I "snipped" was simply excess wording that did NOT ensure 
the RF would goo and stay where YOU want it.
