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.

You might have trouble getting free unrestricted library cards if you don’t live in the area that the library serves. They are usually paid for with taxes and aren’t there to serve people outside their community.

If you’re willing to pay for it, I know that the Ottawa Public Library in Canada offers membership for $90/year to people living outside Ottawa. You may find something similar at other libraries.

The Libraries and Archives of Canada will issue a card too, but you have to visit the archives in person and have a reason you are using the archives and not another library.

Not every package that comes with xfce has a name that starts with xfce4, just most of them do. You may need to identify and remove other packages too.

I think that: sudo apt purge xfce4* sudo apt autoremove

“apt remove” will only remove the packages, not the config files
“apt purge” will remove the packages and config files
“apt autoremove” will clean up the orphaned dependencies
“xfce4” will only remove the DE
“xfce4*” will remove the DE and most of the other packages that come with xfce
