My guess

The left sort of looks like the outside of the cable so I think that’s ground.

    It does not matter. (It does not matter in a “ground plane” antenna either, the radials have nothing to do with the earth other than being easier to mount with the coax heading downward; in fact, radials should not be touching or buried in the earth as they are RF radiators and RF faces high losses in soil)
