Eddie
look at the current in the radiator at the bottom,
its far from near zero as it would be if you model a wire dipole with the source in the middle,

i could be wrong as i never saw anybody model a dipole with a choke at the bottom end but that to me looks like the choke is not presenting a high enough impedance & current will likely flow on the choke and any mast or coax you connect to it.

you could try adding a mast under the choke, make it 1/4wave & see if it carries significant current, just an idea.
