Hi
Personally I am not at all sensitive to the form factor. My use is 99% lab
use and 1% antenna/portable use.
I wonder how many actually wants a small form factor.

I think it depends what you define as ¡°small .
To me at least, a Keysight FieldFox is just about acceptable for carrying
and for use with antennas. That¡¯s approximately 292 x 187 x 71 mm and
weighs 3.0 to 3.2 kg. I would prefer something a bit smaller and lighter,
but I don¡¯t see any need to be able to fit a VNA in a shirt pocket.
We have a RigExpert at our radio club, and I have seen an MFJ around too.
The RigExpert and MFJ are much bigger than a NanoVNA, but in my opinion at
least, they are perfectly acceptable for work on antennas.
Everyone has different priorities. Some want more dynamic range, some want
higher frequency, some want a bigger screen, some want to fit it a shirt
pocket, others want TDR in the firmware ....
Unless you build your own VNA, you will probably never get exactly what you
want.
