Nano VNA like sand on the sea- Who is the "good one" ?

(1/7) > >>

Hi folks,
Quick question:
I just want to play around with a VNA and a cheap Nano VNA seems to be the perfect solution.
However, if you search for it, there are countless variants.
Which one is the "good" one, which one should I get?
Thanks in advance.
Martin

There are different screen sizes and bandwidths etc.
I don't know if there is the one "good one".

I have one of the cheapest (as always) from the "SeeSii Factory Store Store" which seems trustworthy/recommended: a NanoVNA-H.

It has an SD card slot, the inputs are shielded, you can update the firmware from the usual sources and I got a pretty big battery (1300mAh), but don't know if that's standard.

It's good enough for me.
More expensive ones are probably better if you have a use for them.

For the Nano, the H4 is recommended by a lot of people. I just bought a LiteVNA, which is a bit faster than the Nanos.
What is even more important is to buy it from reputable sources. Because there are a lot of interior clones out there. They might be missing the shielding. Or the PCB is not impedance controlled. Or the cal kit which comes with it is trash.

This is the most important factor.  Buy a genuine one.

As you said, they are cheap, and if you just want to play, I don't think it really matters too much.  Later as you refine your requirements, you can always buy something that better fits.   

I continue to use the LiteVNA64 for some experiments.   We purchased ours from:
