Yes. It is also important to remember that a SAFE installation (from a 
lightning and power safety point of view) requires that ALL grounds be 
bonded together, prefereably outside the building. In other words, while 
we must consider the behavior of our ground systems at radio frequencies, 
we must also take into account how they behave at power frequencies, and 
how they will respond to lightning (think radio frequencies). 

There is a discussion of safe grounding in the Power and Grounding 
tutorial that is on my website. All pdf files, no cookies required, free 
download. While it is specifically written for pro audio systems, the same 
laws of physics apply equally to our ham stations. :)

BTW -- sorry to have missed seeing you at Dayton -- I just completed a 
cross country move from Chicago to Santa Cruz, and am totally burned out 
on traveling for at least a month or two. So I stayed home. The good news 
that I'm now about 20 miles from Elecraft world headquarters!
