That antenna looks quite interesting. If someone built that, a picture would help show what you end up with in practice.
I had an elective Antennas/Propagation class in college that re-ignited my interest in antenna design, I cut the cable way back then.
The DTV transition 21 years later had me getting into old designs after I saw some silly junk on the internet claiming unreal reception distances reminiscent of Radio Shack's advertising. The old designs were better but covered a wider UHF spectrum that could be tweaked. Jerrold Channel Master Winegard Finco JFD S&A all made some very good designs even by today standards, all different.
When broadcasting, reduction of standing waves is a factor when tuning the antenna. I have just used a 1/4 wave dipole for VHF and bowtie for UHF via RG-6U about 10 feet from BT modulators. Broadband antennas that are directional are another option, but the best may be a 5-element yagi tuned for flat 6mhz on the specific channel, aimed at your studio.
