[Elecraft] grounding power supply email trail is confusing

[Don Wilhelm]

Jim,

Maybe Eric will not object if I summarize my views in one last public 
post. :-)

There are 3 "grounds" that a ham station should be concerned with:
1) AC service grounding - best to consult with a licensed electrician on 
this one.  Older buildings may need some updating.  Unless you have 
knowledge of NEC, this is not a 'do it yourself' job.  A local 
electrician should know the current code requirements.
2) Lightning grounding - reference the articles in QST during 2002 or 
other authoritative sources (Polyphaser site, etc.).  No license 
required to install, but it must connect to the utility entry ground to 
meet code and be safe.
3) RF Ground - IMHO, difficult/impossible to create with an earth 
connection (but many try), so solve the problem in the antenna field by 
balancing the currents and the RF Ground should take care of itself.

73,
Don W3FPR
