What is the principle behind the "ghost" antenna?

[WRWE744]

With the ghost antenna being about 1/8 wavelength in length, I'm wondering what the engineering of the antenna is. Is there a coil inside? Is it classified as anything besides a "ghost antenna" (such as a "ground plane antenna")? It's a very unique design, and I would like to understand it better.

A lot of ghost/stubby antennas are loaded coils. So efrectively more coil than antenna.

All the ones I were looking at where essential 5/8ths antennas and the gains would match with a standard 5/8 coil nmo antenna with appropriate matching assembly. Funny enough they are almost the same size. The ghost antennas were a tad shorter.

Low Profile. Please note the White Phantom antenna just under the rear window near the top and attached to the rollbar structure. This antenna is a non-ground plane designed antenna.

And these antennae are not "Ghost Antennae", I can clearly see the antenna. They are called Phantom antennae as named originally by Antenna Specialist now called Laird.

I was under the impression they all required a ground plane.

Not the one on my racecar. Talley still has  the ANXTRA4500N antenna. Surprisingly, they're still using the Antenex antenna part number.  Unfortunately, the White Phantom is still the only single unit purchase and the Black is a minimum of 10 unit purchase and that is why I have a white Phantom non-ground plane NMO antenna instrad of the black non-ground plane NMO antenna.

I’ll have to check that one out. Every once in a while I get asked about it.
