Please join us in welcoming Dave Eckhardt, W0LEV, to the role of
co-owner of the nanovna-users group. Most of you have probably seen his
posts to the group. He is well-versed in the use of VNAs and is very
knowledgeable in the areas of electromagnetic fields, antennas, EM field
measurements, just to name a few.

Get. The. Proper. Tool. If they make an insertion/extraction tool it is because it is needed to avoid damaging the delicate connectors on the cable or, worse, tearing loose the mating connector on the board. My father, a tool-and-die maker, told me that if you need a tool for your work and do not buy it, you will pay for it and still not have it. 73, Don N2VGU

Re: Running NanoVNA-App on Raspberry Pi
It looks like you may have a math library issue, maybe indirectly through
some other computation library used. Seems like it may be using more
significant digits, or not rounding in the same manner, making the axis
labels annoying.

One of the main reasons I got a demo board was to get some experience/practice working with the U.FL Connectors. My most recent radio has a lot of them and figured it's better to practice on something small and cheap.

Try this. There is a link to purchase directly from the vendor.

Hello, you can find some application information here: /g/nanovna-users/wiki/16592Most important is the handling of the small RF connectors U.FL/IPX. 73, Rudi DL5FA
|
The kit can be used to familiarize a new user with the shape of the VNA's responses to various types of circuit elements but is not too useful otherwise.
The IPEX connectors were designed for one-and-done use and will wear (or break) quickly with repeated mating/demating cycles. Getting the connectors unmated can also be tricky without the special little tool.
Having used VNAs since the '80s, I wouldn't buy it myself but for a newcomer it may have some value as a learning tool.
