With an unmodified 15/60 NST and a static gap, I am able to get 60" peak
streamers, so there is room for improvement.  Adding additional NSTs in
parallel would help but I think there are things you can do before
adding more power.

I would suggest a larger top load than 4"x14".  I used a 6x23 plus a
4x15 and it still could be larger.  A newer 7x30 that I made seems
right.

What is your gap set to?  If it's too narrow it could hobble
performance.

Running a 15kva 60ma NST.
Primary 13 turns 1/4" copper tube with 3/4" spacing.
Using 10 awg wire to tap primary.
Secondary 8.5, 22awg with 933 + turns for 23".
Caps MMC 3 parallel strings of.056uf 1600V metal Polypro, x12 each per
string
for a total of 19,200volts.
Toroid 14" diameter X 4" high.
Using a static spark gap blown by my 3.0 horse shop vac.
 
I was able to get 12" solid 1/4 to 1/2 thick streamer to a ground post
once I
tuned it.
 
I am kinda disappointed thought it would do 2 to 3 feet.
 
Do I need more power?? or a bigger toroid.  I should be able to get 2 to
3 feet
out of the coil that size.
 
If I put 2 15kv NST's in parallel will this make much of a difference??
 
Or do you need a pole transformer to get this performance.
 
 
Thanks
