This is from the 3rd edition (1972)
of the ARRL VHF Manual, p198-9:
Developed by W1FVY and W1IJD
Consists of 3 elements, each
element made of 1 wavelength
of wire. The elements are
formed into (non-circular) loops.
The loops are in the horizontal
plane, and oriented at 120? angles,
like a cloverleaf. The loops
are driven in parallel with each
other, and in parallel with a
matching stub. It is "nearly
as effective in all directions
as a horizontal 1/2 wl dipole
in its favored directions."
They suggest stacking them to
get omni gain.
For 10 meters, the total diameter
would be 20 feet. It easily
covers the 2 meter band and then
some, so it might be OK on 10,
which is twice the BW.
Hope that helps. I don't know
anything about the big wheel: I'm just
reading to you from the book.
It occurs to me that it might
basically act like a circular
loop fed in 3 places with
open wire line.
