Re: The 1500t secondary myth

"The ratios of pri-sec inductance (i.e. turns) and inversely,
capacitance
(your point) both yield the same theoretical voltage gain at resonance.

My take is that perceived performance (streamer length) is not
necessarily correlated with top load voltage, theoretical or otherwise.
If it was, I think small top loads would fare better than they do.  The
recent discussions of streamer-load to secondary impedance matching may
hold promise.

	I think that what counts is to maximize the power delivered to the
streamers, which seems to me that the real matching is to the effective
primary impedance as it rings down.  Since the coupling factor depends
on kQ, it's necessary to keep the secondary Q high enough to maintain
sufficient coupling when loaded.  I'm surprised that it can be as low as
6, but I guess that would work out for coils with relatively high mutual
inductance.
