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

A dipole doesn’t have a ground plane like some other antennas. A dipole is a balanced antenna and both sides work off of each other equally.
With that said, this one is probably used for receiving and if one end is connected to the electrical ground (different thing from antenna ground plane) then it’s going to be the left side with the uninsulated wire most likely.

A 1/4 wave monopole above 1/4 wave radials is also a balanced antenna. unless the coax is carrying common mode currents, the antenna is balanced.
