Hi Pete,

Did you ever try an L network?

First iteration of my shunt feed was C at the base in series. Tuned 
for minimum SWR and then cut top loading to get SWR down further.

Then, I had an "ah-ha" moment. Why not use a step-up L network:

series C and parallel L at the antenna side?

I was able to tune out both reactances this way w/o having to cut top loading.

Makes a lot of sense to me.
