Well, "John Doty" in the reference above says:

Any *unshielded* [my emphasis added] conductor in your
antenna/ground system is capable of picking up noise: the
antenna, the "lead-in" wire...

First of all, isn't the "lead-in wire" (coaxial cable in this
discussion) -shielded- ? So according to his -own- statement, coax
shouldn't have to be buried, at least from a noise mitigation
viewpoint.

Doty continues:

You can keep noise currents away from the antenna by giving them
a path to ground near the house, giving antenna currents a path
to ground away from the house, and burying the the coaxial cable
from the house to the antenna.

In the 1930s, Bell Laboratories, while investigating power line
influence on telephone cables, proved that burial had NO effect on
noise being induced into the telephone cables; i.e., 20 feet of
aerial separation, from a noise standpoint, was exactly the same as
18 feet of aerial separation plus being buried 2 feet deep.

Hmmm...should I believe "John Doty" or Bell Labs? You're a smart
guy -- I'll let you figure that one out for yourself. :-)

Without agreeing or disagreeing with your arguments above don't you
think you should be able to come up with your own explanations and
understandings on the subject?

Let's examine what you just said above.

You want me to re-invent the wheel, re-plow the same ground and
duplicate the work already done by the PhDs at Bell Labs?

To put it another way, you imply it's OK for RHF to quote "John Doty"
but that it's not OK for me to quote Bell Labs. This is one of your more
brilliant comments, Sparky.

Why should we read you posts...

Nobody is forcing you, Sparky.

...when we can just go read the person you reference?

If you -don't- read my post, how would you know what person I am
referencing? Again, positively brilliant of you, Sparky.

In any event, the Bell System Practices (BSPs) addressing this issue,
still in use to this very day, are proprietary. However, I imagine you
could reference the public 'Bell System Technical Journal' issues of the
era. And, yes, please DO read the "person" I reference (although the
Bell Labs are not "a person"). You will then find that what I say is true.

You think you somehow improve the information?

Please point out where I ever said or implied anything about "improving"
the information. I simply quoted the applicable work done by Bell Labs.
Period. There's just no end to your brilliance, Sparky.

I think reading your posts are a waste of time.

So why did you read it, hmmmm? A sign of mental illness is repeating the
same mistake.

And suit yourself, Sparky...you can always fall back on your time tested
Plonks. ;-)
