As to gull wing radials, Rudy Severns has looked at these too:

Rudy's work is a treasure trove and I think I have everything he's
written in a folder on my hard drive. Believe me, considering how
difficult it is to lay radials in my cactus patch, if I thought gull
wings would be useful I would have used them. I don't.
Rudy shows gull wing down only 0.65 dB and comments that "radically
changing the radial geometry does not seem to have a major impact".
So I don't understand your remark that gull wings are not useful.
The reduction in drive impedance can be mitigated by increasing the
height by about 3 feet. I don't even have cactus but would never again
run radials on the ground now that Rudy has educated us.
