Terry, List,

Regarding streamer capacitance loading affect on PRI/SEC frequency;
It would seem that Fo would be unaffected by streamer capacitance due
to the fact that by the time the streamer emits/grows all the charge
deposited on the Cs possible is there and the streamer subsequently
emits and grows from that charge. The streamer suspected of enlarging
Cs is there connected for only ~10-100 nanoS's each<<1/Fo  Is it possible
that as 100's of streamers are producing more ozone that the dielectric
constant is changing around the coil - could that account for the lower Fo
required to maintain long discharges ?

        I originally didn't think this capacitance loading effect from
streamers was valid.  However, I now feel that the scale I tested at and the
scale (Nemesis) that Richard tested at, are not comparable.  More testing is
needed with high power and BIG streamer systems to verify this effect.  I
still have my doubts but I don't have any data to verify them.
