Has anyone produced a structure map for V1.2.14 firmware? If so, where is it located?
Thanks,

Re: Which NANO VNA To Buy ?
I have the H version 3.5 older software has small screen.. H4 larger screen
would be my choice for what we want to use it for. Other models have either
no case or more rugged case and have extended testing capabilities beyond
my scope. I'll dig into my notes a little later to send you more info. And
cautions regarding manufacturer.

Re: Which NANO VNA To Buy ?
I might as well put in my .02 cents worth. I am pleased with the new Deeplec DeepVNA101. This is the current evolution of the VNA-F. It has the 4 inch screen and is more visible in the outdoor sun than others. The biggest advantage of the DeepVNA101 is that it has a rotary encoder in place of the rocker switch for adjusting values. This makes changing parameters and frequency than most other VNA's in this price range. The dynamic range has been improved over earlier versions. The big PLUS is the ease of upgrading firmware. IN other units you have to work to get the unit in the DFU mode and then load the new firmware. In the DeepVNA 101 you just use the USB cable to plug into the computer, download the latest firmware file from Deeplec, and place it in the root directory of the DeepVNA101. Next turn the unit on and off and you are ready to go. You can purchase the unit from Deeplec.com or even Amazon. If you order ANY VNA from Amazon make sure you are getting and original and not a knock off clone. *Clyde K.

I've been thinking about purchasing a VNA. I mainly will need it for HF
and VHF and I will only be using it once in a while for tuning a few
antennas I have in my attic.
I have been looking on Amazon and eBay and saw so many versions and also
so many different prices.
Saw V2, V4.3 and SA, H4 ? Its really been overwhelming. !
Any ideas on which one would be best for me ?

Re: Which NANO VNA To Buy ?
Well, I bought the Seesii H4 v4.3 off Amazon, that came with everything needed and has a very good battery. I consider it a good purchase. I have not had one issue with it.

Frank,
Order your H4 from L and R Electronics. They are trustworthy. I got mine there.

Re: Which NANO VNA To Buy ?
I have the same needs. Started with the first H2 models. After two years upgraded to an SAA2. In all cases I rarely use the onboard screen. I use the computer.

Re: Which NANO VNA To Buy ?
My H4 came with pigtails included.

Here's the URL for the Zeenko store on Aliexpress, for ease of reference:

Re: Which NANO VNA To Buy ?
Clones of the NanoVNA-H and -H4 generally don't work as well, and they
aren't much cheaper. The best US supplier is R&L Electronics. You can also
order from the Zeenko Store on AliExpress; that is Hugen's own store. R&L
costs a bit more but you get it faster.

Yep -- I'd get 6 or 12" pigtails rather than adapters. Strain relief is a good thing. You'll quickly find that even RG-8X is much stiffer than the SMA connectors.

Saw V2, V4.3 and SA, H4 ? Its really been overwhelming. ! There are... Any ideas on which one would be best for me ? A couple ideas to think about: Are you looking for something to use by itself, outside? Then one with a 4" display is better than one with the 2.5" display. On the other hand, if you'll be using it mostly hooked up to a computer, then the smaller screen (cheaper) one works just as well. The original NanoVNA is pretty robust to damage from ESD, since it has resistive bridges/pads on both ports. The NanoVNA V2 (aka SAA2) which goes up to 3 GHz(V2_2, V2 Plus) or 4 GHz (V2Plus4)has RF switches on the ports which are fairly sensitive to ESD. but has generally better performance. If you're not doing microwave stuff - I'd go with the older more robust vanilla NanoVNA Also, there are some differences in what kind of battery (does it come with it installed, or is it separate) and some have a SD card slot, some don't. If you're measuring stuff using PL-259/SO-239 UHF connectors, get yourself some SMA to UHF pigtails. You can also get adapters, but the pigtail calibrates out, and provides essential strain relief so that 2" hardline to your 80meter 3 element yagi doesn't break the tiny connector on the NanoVNA.
