I forgot to mention that initially NanoVNA-App would not load the renormalized .s2p file. I had to manually change R 330 to R 50 in the # line to get it to load. Before I discovered this, I used to create the plot I posted. I'm going to leave the renormalized impedance in the file since it's correct. Maybe someone will modify NanoVNA-App to be more tolerant.
It would be neat if NanoVNA-App would do the renormalization itself from forward and reversed .s2p files or live measurements.
