I have the plain wave antenna for the top voltage (no calibration) 
and a Pearson 110 current monitor on the ground rod like this:

I set the scope for 50 ohms input impedance so that bandwidth should 
be pretty good to 20MHz.  The spark gap was about 10cm.

Here is a typical higher speed scope capture I got:

The scope is 100MHz.  The yellow is the top voltage from the plane 
wave antenna (not in a real good position sitting on a trash can 
under the table...) and the blue is the current from the Pearson.  It 
looks like the big spark takes place in about 50nS!  The raw 
numerical data file is here:
