[RFI] Shielding a ground wire

[Timo Toro]

I did fix my problems already. My antenna systems are not incomplete. 
Of course more and higher masts would be nice, hi.

But if I run over 1KW to my 4el Yagi on 40m and my PC stops working, 
I have to fix that problem. I did not use the band aid either. 
Nowadays my ham shack is more like Faraday shield, hi. And lightning 
safe.

I still like to use word "grounding" meaning low impedance route to 
common point near earth potential.
