Dear Art: Indeed, fishing poles are a main stay of amateur radio - and
very good value.
As you have pointed out, I am a patent attorney (who is not looking
for additional work). I am also a licensed professional engineer in
Michigan. These two professions facilitate my "day job."

As a follow on to your note about a certain Rohn tower (with an
aside that their commercial products always conformed to standards - I
have checked some of their calculations) I note that Heights Tower once
included in their literature an accurate account of how to calculate
"strength" and wind effects on their line of welded aluminum towers. It
was clear from what they presented just what assumptions were being
made. Such a full disclosure is commendable.

Mac,
I understand your line of work is a patent attorney
but it easily could have been one as a mechanical engineer.
Your description of antenna mechanical design is outstanding.
