That would be very interesting! Let me know if you find it.

There's something I've been looking for, too. I recently saw an article in
a proceedings or compendium that gave a way to calculate element length
correction factors for elements going through metal booms. I have seen
other articles on this but I only want the article that has been in a
proceedings or compendium in the last year or two. Maybe one of the recent
ARRL antenna compendiums? I just can't remember where I saw it.
