Re "delay"
Puting a 'reactance' in series was done with an antenna
in that capacitors were inserted along the radiator..
Beaszely determined by using hiscomputor program that it did nothing to
enhance the antenna despite claims to the contrary. So yes, I agree there is
a phase change but that is where I stop

What is the basis of your suspicioun regarding 'Q' ?


The flux from each loop flows across all the other
loops. A web search for "pancake coil" turns up some
interesting stuff including one company's claim that
their coil-on-chip process turns out coils with double
the 'Q' of pancake coils.

Incidentally, a pancake coil doesn't solve the magnitude
difference problem between current in and current out in
a standing wave antenna. It may not radiate but it certainly
has a delay through the coil which is what causes the current
in to be different from the current out in standing wave
antennas. This is explained on my web page at the bottom
of the page.
