While this provide some details regarding your antenna, it is not
sufficient
for me to visualize it.

take an aluminum foil dunce cap, wide a curly pigs tail helix inside of it
and feed it with coax. most likely he attached the shield to the foil and
the center conductor to the helix, so all he has is an ugly dipole all
folded up on itself at hf. he would be better off putting the dunce cap
over his head to prevent damage from the brain probes.
