So this flute thing is essentially a bi-cone EH antenna.  Somehow the cosine 
derived flute shape helps in satisfying the requirements of the Poynting 
Theorem, to align the E-H fields in time phase, and on and on.

One of the more controversial antenna types, judging by the range of opinions 
from  “it must be magic”, to "it’s the coax that actually radiates", to “it 
works and is simply misunderstood by people too set in their Hertzian thinking 
to understand the new and brilliant concept”, and so forth.  I don’t know 
enough to know.  I do know it wouldn’t be worth ten grand to find out :-)
