I'm brand new to this group and brand new to the nanovna v2 Plus4 which
I just received today.

Are there any do's or don'ts regarding adapters?

My needs are likely never going to be higher than 470 MHz. Primarily 6M,
2M and 440.

I use pigtails about 6-12" long with small diameter coax - that way
there's some strain relief between the connectors on the Nano and what
ever I'm hooking it up to.

I then calibrate at the end of the pigtails.

Yes, if you calibrate at the end of the short coax lengths, as far as I
understand it... you take them out of the equation.
have to say that the fragility of the SMA connectors is the reason that I
got the version with the N Type connectors in a steel case.
I recently compared the NanoVNA SAA2 with a RIGExpert Zoom 650. They were
so close in their outcomes that it was negligible.
The NanoVNA was a hell of a lot cheaper and for antenna work... mainly VSWR
work... is perfect.

I've also compared the NANOVNAs to the HP 8753C cal'ed with HP precision
loads. The agreement between those is amazing.
