Hi Gene,
So your a rocket scientist!!!
I'm just a wiseguy!
I would reverse the connection on the ant primary. The diagram shows the top of the winding going to the ant post. Would also add some more turns say 25 total. Should be near the bottom of the secondary. You could add some C between the top of the pri and secondary like 10-50 mmfd.
