Your antenna works because the radio metal case, power cord and the shield of any accessories connected to the radio are acting as a counterpoise. You don't have a free space antenna setup.

I'm not building an antenna. All I want to know is if the NanoVNA can show me return loss peaks with a single length of stranded wire. Nothing more. I have an antenna and it works just fine. Don't need an antenna.
If the NanoVNA cannot do a single wire return loss reading, then fine.
