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.


What average gain did you expect? In case you had in mind that average
gain would be a big positive number, an antenna doesn't create power,
average gain (ie gain averaged over a sphere) MUST be less than 0dB if
it has ANY loss, mustn't it?
