Emmett,

You are correct - connect the bottom of the secondary, the nst case, the 
center electrode of the safety gap and your strike rail all to your main RF 
ground.  Do not connect the nst case to AC line ground.

The strike rail needs to have an inch or two gap in it to keep from looking 
like a shorted turn to the primary which would waste power.
