To you, me, Al, and just about everyone else that was directly involved as well.

Ah, the written word, with its proclivity to completely avoid misunderstanding
on every side...... ;-)

Apology accepted, and I'm not outraged, but I did wish to point out to the
casual reader that although this particular site appears to have certain
characteristics, all is not as it appears.

and, I think many of us have run into such at one time or another.

After the fact, after the money has been spent, some things that were not
known pre-construction become glaringly apparent.
No. Soil testing wasn't done, but.....
The 30 foot hole that became the stick foundation did reveal a couple things that
got an "Oh, yeah." from some locals later.
I was later told the site is fill, and the fill came from an old highway project.
As such, it's mostly chunked concrete, and such.
Further, based on experience with other stations in that market,
the conductivity is not that far below measured metro Dallas
even though it's far below M3 for that same area.

This stick has not proved to be too tall.
It was modeled prior to construction, but performs not even close to the model,
except very close in, as I understand that part.
Al is much more qualified to comment on the specifics.
In this case, it's entirely attributable to poor ground conductivity, especially
in close proximity to the site.
