Ah.. not the best place from a performance standpoint...

You might try putting a counterpoise under the coil to provide a good RF 
ground.

You might be getting loss in the caps.. saltwater caps usually use glass 
bottles (which are also lossy)..  How thick is the plastic in the 
bottles? (you might be getting pinholes or corona discharge)

The NST will usually have a name plate that gives voltage.  Or, you can 
set up a simple spark gap and measure it. 70 kV/inch in a gap with 
roughly uniform field (not a needle gap..).. If you have a couple smooth 
round things about an inch or so in diameter (drawer pulls, doorknobs) 
they make good gap electrodes.
