Guilty. It was a homebrew.
A 40 conductor ribbon cable soldered to the slot 4. Ribbon connectors

Much can be done with nearly invisible antennas, and your local Amateur Radio
oerators can be of help.
A lot depends on if you are renting or owning.
A homeowners' association can pass some restrictions, but local ordinances
can only ban unsafe setups. By definition, Amateur Radio is licensed
as a Public Service, so Amateur Radio antennas or equipment can not be
banned as a public nuisance.

standing, "no guy wires" tower, right at the edge of the property.
