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.
Way back when, I had a Palm Pixie, which ran WebOS. While it wasn’t FOSS, if you turned on developer mode, you would have full terminal access to the Linux system it was running.
I think HP eventually made it open source and now LG uses it for their TVs. But that phone’s OS was one of the best ones I had seen at the time.
