I intend to find out what the proper nomenclature is for this antennae assembly. If anyone knows, please let me know.
In this series of photos, the antennae is mounted on the rear hatch with the wiring running below the antennae and through the hatch. I do not know the path of wiring on the inside of the vehicle. Undoubtedly, it ended at the radio rack between the driver and passenger.
The antennae and base is a matte black. The mounting plate was gray in color.
