Hello
Here is my reasoning regarding this problem of visibility of the NanoVNA screen outside. This case only applies to an antenna that will be connected to the station by a coaxial transmission line.
I will make my measurement to the NanoVNA from the station by doing an OSL calibration on the end of the coaxial, which may not be in its final position (it simplifies) but within reach. I use the nanaovna-saver software which thus connects my PC to the nanoVNA.
Then I connect the rest of the antenna, in real position, on this end (where I did the OSL calibration) and I still make my measurement with nanaovna-saver.
The measurement therefore corresponds to the whole: antenna + external conductor of the coaxial + any additional device such as chock-balun, ground connection, etc. The interest of taking into account the induction on the coaxial line seems fundamental to me.
Measuring the antenna, totally isolated from its feed line is not useful; it will never be used in this configuration.
The advantage of the proposed method is that you see your curves in the shade and that you easily save the .s1p files
