Now I understand the loading coils on a bugcatcher are not resonnant,
they're just loading coils.



They ARE resonant, otherwise what's the point in using one?

A short antenna exhibits a principally capacitive reactance that with
the addition of a loading coil resonates the structure leaving only
the radiation resistance behind.

They are NOT resonant at the frequencies of interest - making antenna resonate
on that frequency. If they were, they would act as a trap and "disconnect" rest
of the whip beyond the coil. And that's the truth, fact, reality. Uh, huh?
