Conical Secondaries

List,

A few coilers have built cone shaped secondaries, such as the one at
Griffith Observatory and the clone of it Bill Wysock built.

Question - other than aesthetics and perhaps saving some wire, are there any
technical advantages or efficiencies to be gained?  With all the discussion
of flat spiral secondaries, let's give conical secondaries their fair share
of interest too!

(If anyone has any practical experience building a conical form and winding
it without the wire slipping loose, please share it with us.)

Thanks,
