However, loaded mobile antennas presumably radiate, at least a little, and
my analysis (and W5DXP's discussion of angle lengths of transmission lines

This makes me wonder.

The current conditions for a mobile antenna can be simulated
by a lossy transmission line made out of resistance wire.
The equations simply include the losses.
