i would have used n sockets ;-) ... but i have a v2 that goes way higher in frequency as the older nanovna
but ok ... nice work
do you have a bigger battery also or a second one soldered in parallel?? (wire bridges will do fine)

The following is a copy of my post of 30th August 2021 which illustrates my solution to the enclosure/connector issues:
The attached pictures show my solution to the SMA issue.
1) BNCs match all my other test gear removing the need for adapters
when interfacing. Indeed BNCs are the standard connector used for
professional test gear up to a few, GHz. (Perhaps 10GHz - Have to
check that).
2) Any risk of straining the SMA attachment point to the PCB is
eliminated.
3) The additional weight of the enclosure reduces the risk of the
nanoVNA being dragged off the workbench by the attached cables.
4) The aluminium enclosure adds a measure of screening - probably a
marginal. benefit.
5) The number of connection cycles permissible with BNCs while not
infinite, is far, far greater than the the very small number of
connection cycles specified for SMAs (in the hundreds if I remember
correctly).
The enclosure is made from extruded aluminium "U" section, readily available from eBay, with suitable apertures cut. I'm not sure that the reference planes for the BNC calibration pieces are perfect, but empirically, the results are the same as those obtained with the calibration devices supplied with the nanoVNA.

IF YOU REALLY HIT THE USB CABLE THAT TINY 2.8 INCH UNIT WILL FLY ACROSS THE ROOM HI HI
buy a 4 inch screen and print a bigger case maybe??
diSlord is experimenting with even bigger (7 inch) screens on the v2!!!

I recently purchased a NanoVNA (with a 2.8 inch screen). I was
wondering if anyone has designed/printed a stand for the
NanoVNA???
I'm looking for something that I can put the end of it into (so that
the SMA jacks are facing up)? so I can attach an SMA antenna
for an HT to it.
With a stand... I won't have to worry about the NanoVNA falling
over if the USB cable between my laptop or tablet gets hit or
moves (more of a problem if holding a tablet) and since it will
keep the NanoVNA from falling over... I won't have worry about
anything touching the antenna to affect the measurements.
Thanks,
