Sorry I was unclear. Let me put it more simply. First I am in full
agreement with your conventional wisdom comment. Much of the
conventional wisdom is not wise. My group grope comment and angels on
the pin apparently didn't communicate as well with you as the humorous
agreement I got in a couple PMs. I was indicating that a lot of folks
with a lot of misconceptions, not unlike the folks debating the number
of angels on the head of a pin, could profit by the equivalent of
counting angels with a microscope to get at the reality of the situation
which in this analogy would be to read the Motorola pub.
My obviously misunderstood remarks were in absolutely no manner intended
to defame the august gentleman to whom you refer. There is no need to
defend him as there was no attack on him or his credibility. If anyone
were to be offended it should be someone who casts himself as a member
of the group grope NOT in favor of using the microscope and finding out
the ground truth.
Just in case I haven't made it abundantly clear yet where I stand allow
me to express my heartfelt thanks for the posting of the Motorola
document which contains both science and engineering information that
should put ignorance and superstition behind. Ditto the reference to the
Polyphaser information.
If there is any residual doubt regarding where I stand on this issue,
please contact me off list and I would be happy to enlighten you.
Although I have no clue how what I said could be construed to be an
attack on Jim please Jim accept my apology for just in case I am too
stupid to perceive my own transgression.

Patrick,
Ham radio "conventional wisdom" is full of misconceptions, and
grounding is one of the greatest. These misconceptions lead most hams
to do dumb things that are expensive and wrong. They can also make
lightning damage more likely, and make hum, buzz, and RF noise much
worse.
Understanding what matters and what doesn't with grounding isn't
"angels dancing on the head of a pin," it's what's safe, what works,
and what doesn't.
In case you don't know, Jim Lux is an engineer at JPL, the guys who
put those rovers on Mars. He's also a contributor to the ARRL Handbook.
