This whole topic area seems to be eternally confused and confusing and
I'm in the parade of the confused. On a common sense basis I
absolutely agree with your connecting the station grounds to the
'lectric service entrance ground for the reasons you've stated.

But somewhere along the line somebody in the ham groups stated that
the National Electrical Code states that there shall be one and *only
one* grounding point per power drop and the neighborhood code cops and
the insurance companies reportedly get stiff about it.

There is a whole lot of misinformation regarding grounding. An
interesting mental exercise is taking a tower say 50 feet from your
house. According to some, in order to comply with NEC, the tower has to
be grounded by sending a lead back to the house to that single ground
point. I guess they want to insulate the tower base from ground - no
ufer's here, thanks. Sounds like a disaster waiting to happen.


The good folks at Polyphaser have some excellent Technical notes. Kept
me busy a long time reading the stuff:

Of particular interest is Ham Radio Station Protection:

It is largely about lightning protection, but has good stuff pertaining
to grounding.
