I'm putting together a homebrew mobile antenna based more or less on
"20 dollar mobile antenna" that appeared in QST some years ago.

For those not familiar, the antenna consists of a tapped coil at the
bottom, a spiral wound lower section, a tapped loading coil, and an
upper stinger.

My question involves that spiral wound lower section. What would this
be thought of? As antenna below the loading coil, as an inductor in
addition to the other two, or some sort of hybrid of antenna/inductor?

How would this be modeled in EZNEC?

Apologies in advance if this was an incredibly stupid thing to ask! 8^)
