Maybe you could try a product called "Gorilla Glue."

The RF current flows into the base and from there into the tube. I
don't think putting an insulator between them is a viable solution.

I have thought about some conducting epoxy, thinned a bit so it seeps
in, but I am not even confident about that.

if the base is big enough in thickness, how about making a small hole
thru and thru the bottom of the whip and the base then pinning it with
a piece of wire run through both? If you were to sand off the plating
at the bottom of the whip, you will most likely find it is brass or
some other alloy. A thin piece of brass or copper wire, or a thin
brass screw would then take to solder along with the whip where the
plating is ground away. This would hold the bottom and the whip fairly
well together.

Right you are!

Previous attempts to heat the base and flow in solder failed, so I
assumed it was steel.

Turns out to be nickel-plated brass:

So, I should be able to drill a small hole and solder in a small
copper or brass pin. Or grind a small crater and let some solder flow
in.
