My design utilized Phenolic flat stock so the transposed feeder system, the periodic cell of aluminium tube elements were all isolated from the aluminum boom because the entire cell was RF and DC insulated via the Phenolic plates.
This allowed the boom to be dc grounded without disturbing the cell function or choke technique at the feed point.
This technique addresses the tennadyne vulnerability before tennadyne ever designed one.
The boom a 2" dia tube was a mounting structure to correctly install each of the plate to element brackets and facilitate the proper alignment.
The apex pair of cell elements were split and fed.
The boom cold to the feed line.
I do not like using the boom double duty as strips serving as the transposed feeder system for 180 degree phase shifting
Although I do endorse wide diameter strips from butt end of each element to next crossover point.for that function.dedicated to the ends of each for the purpose of transposed feeder methodology rather than wire.
Incidentally the antenna was fabricated as designed and intended to work and understood to not need a tuning mechanism.and it did not need one upon the top final position.
I installed it and was matched properly in the first place because I designed it that way.
I did feel compelled to take a peek at the swr prior to the installation and did point the apex toward the zenith and nothing remarkable was noted.
I like my design that avoided those suggestion of precaution in the first place....
