I see a loop antenna here, albeit an 'E' loop sitting on it's own insulated above ground platform..
You can also see it as a top loaded vertical..
To me it makes the most sense to feed just like that and above/away from lossey ground..
The first thing is that you pick up 3 db just for not feeding half the power in to ground radials..
Two paws up on this one.. Plus the big fat vertical part is relatively ultra low 'R' where most of the current is..
The effective height is probably a pretty good number too..
It would be the best mobile antenna to ever crown the WA1HLR cadaverlac, yessir a mighty pretty 160m mobile antler fer sure..
I'll see your king and raise you one solid 6" copper strap
vertical 'I' loop and get two nulls for free to protect those
other AM stations and therefore allow you to run MORE power..
Yanks come up with the darndest things!!
Next time, see the old wire cage vertical @ early KDKA and what
it did on 1020 kc...
Tom Monahan W3WGM has the whole story on that one.. WOWZA

Hi
Possibly interesting. I started watching the video and quit after maybe 5-minutes.Talking-heads BS !!
I located this Patent Office info for the HEBA antenna ===>
that may have more useful info.

The HEBA - AM's Real Estate Relief - with Grady Moates - TWiRT Ep. 460
TWiRT - This Week in Radio Tech
Grady Moates is a “hands-on” broadcast engineer. Known widely for his audio processing expertise, Grady’s attention has more recently been on proving the performance of a novel antenna design. The High Efficiency Broadband Antenna (HEBA) - after years of additional research and real-world testing and proving - is now FCC approved. Grady explains how a HEBA help AM stations, especially those with real-estate opportunities.
