Re: RF ground

["sundog" <sundog-at-timeship-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Yep.  A biiiig hammer.  a 9 pound sledge if I remember correctly.
I put a block of oak on top of the pipe to prevent it from folding
over or flaring, got out the ladder, and proceeded to pound for
around a good 1/2 hour.  No salt, no expensive solid copper rod.
Just a 8' piece 1" copper pipe.  Cost me $8 at home depot if I
remember right.  It *is* a lot of trouble, but once you fire off
your coil, and don't toast something in the house (or in my case,
turn on all the speakerphones), it's worth it :)  Plus it doubles
as a high-voltage ground for a shorting wand.
                                                            Sundog
