Default New antenna

The patent, US 7187335, is a real hoot. I especially like the part where
he describes doubling the bandwidth by adding a parasitic winding
intertwined with the base coil helix.

Do you suppose his antenna is in equilibrium? Could proper application
of Artsian-Gaussian theory improve it even more?

What? You don't see cutting the capacitance between winding turns as
causing some measurable effect which in turn affects a property of the
antenna proper?

Thicker conductor(s) usually means a measurable gain in bandwith, with a
parasitic element in such close proximity to the major element, a gain
in bandwidth is not that difficult to propose and attempt to prove/disprove.
