I've never needed an rf ground for a base fed half wave. A decoupling
section with radials is an option to reduce feedline radiation..Not
required to work though. MK

You lost me Mark. You have a vertical half-wave wire fed at it's base.
You have an unbalanced L/C network which matches the very high
feedpoint impedance to, say, a random length of 50 ohm coax. What do
you do with the coax braid and the ground side of the tuner?
