Default Rule of Thumb for coax chokes

So what would you call the frequency at which a coil alone
is resonant when mounted as a base-loading coil over a
ground plane?

Cec,

I would call it the frequency at which the coil alone is resonant when
mounted as a base-loading coil over a ground plane.

It would depend on whether the ground plane was a bicycle or the deck
of a super-tanker.

That's the self-resonant frequency "in situ".

Wouldn't that just be a coiled-up whip?
