Jim sez: It won't be a resonant antenna. But the car's body
will improve the signal seen at the input to the radio.

Tha's what Jerry has been trying to tell you. If by resonant you mean an
antenna that presents a transmission line with its characteristic
impedance -- then a whip, even though it is too short to be a 1/4 wave
dipole, will still be a better antenna if it has an approximation to a
ground plane under it. Jerry's car is part of the antenna!

Ed,
You're on it like a cheap suit! A ground plane must have an area at least
1/4 lambda ^2 to be effective.


It doesn't *have* to be a resonant system for the antenna
to work.
