I forgot to mention, by feedpoint, I mean the point where the coax begins.
If a dipole, right after the center insulator, if a vertical, right after the coax starts, and on the coax, if an antenna that has a matching transformer on it, after the matching transformer.

Hi again,
Once you have added the ferrite material, check by putting the nano down, and picking it up again.? If the frequency still slides around try increasing the number of turns until you see no, or little, change in frequency.
Once you arrive at a point where you are seeing little, or no change in frequency, it is time to tune the antenna.

Interesting. So should I be sure to avoid contact with the nanovna while observing or tuning the antenna swr?
