Actually, maybe it doesn't have gain compared to a halo... I'm not
really sure... I have an inconclusive 6m Big Wheel EZNEC model with an
average gain problem... though at this point it's only showing a -0.5dB
average gain or so, and impedance and gain seem constant with
segmentation changes, so it's probably not so bad.

I made it back when I was considering building one and modified it a
little bit to make the avg. gain work out better.

Anyway, if anyone wants to try to get it to work reliably, there's a
model at

Hi Dan,
A model I did some years back showed gain very close to a dipole, much
better omni pattern than classic halo/loops and about a dB better gain than
the loops (once you average their gain around the full 360 azimuth).
This from memory.
