Hello Doug,
Yup, your question is off topic for this group, but I hope the moderator will
tolerate a few replies to your question.
When I read your question and look at your callsign & QRZ listing, I speculate
you fall outside the "very seasoned 'professional' amateur operator" who
populate this forum! :-)
I strongly encourage you to try your hand at building that antenna, or any
antenna, for that matter. Whether the result is a stunning success or hardly
outperforms a standard dipole won't be as important as what you will learn
along the way! Fabricating an antenna is similar to building an amplifier
because it combines mechanics/fabrication, electronics/RF theory, and of course
a bunch of magic!
You may want to join the TowerTalk reflector because that groups focus is
primarily tower and support structures, but they also get into antenna
discussions from time to time. Oh, and of course, how to determine "true
north", bird deterrents such as "plastic owls", and how to prepare PL-259's and
seal them properly. Fun stuff!

All,
This is off topic for this group, however what is the consensus of the 17
meter "Wonder Bar" antenna?
>From a stand point of low wind load and some directivity, this looks like a
good project for my QTH. I do have questions concerning tuning and spacing of
the elements.
First off, is this beam actually worth building?
I own the MFJ 249 (pre B version) and a Grid Dip Meter. I would like to better
understand how to tune the elements for resonance.
There were no formulae given or stated for construction of this beam or
construction of a similar beam on another band. A Google search did not yield
much information. I was contemplating ordering the older QST articles that
were referenced.
73,
Doug - N9XTF
