Do we need a VNA for 5 ohms and an other for 500ohms. Are they possible. Lets forget about 5 or 500 ohms attenuators, coaxials and such. But would it help if VNA is made for other impedances.

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

The wiki page Home ( /g/nanovna-users/wiki/12336/174009 ) has been updated by Ho-Ro <homuth-rosemann@...>. *Reason:* Mirror/clone of DiSlord's source repo with binaries of his

I provide unmodified bin and hex binaries of DiSlord's latest version in a branch of my clone, for version info just check the commit message - currently version 1.2.15:

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

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

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. -- -VA7WNW-

To be contrary; Not as low cost, but I would suggest the German/English VNWA I have them all, and on the bench I prefer to use the VNWA Lester B Veenstra K1YCM M?YCM W8YCM 6Y6Y W8YCM/6Y 6Y8LV

Frank, Order your H4 from L and R Electronics. They are trustworthy. I got mine there. https://store2.rlham.com/shop/catalog/product_info.php?products_id=75145&osCsid=ck2dbsgilpsrvcav3rqp85ggl3 Dave

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.

My H4 came with pigtails included. Mike -- Mike

SV4401a. This VNA has a 7" display

R&L worked fine for me. Mike C.

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

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

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.

There are... 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

Another question is sources to buy from. I have seen Information stating all nanovnas from Amazon are clones. Are clones safe to buy Harold WE4G

I agree, you can't go wrong with the H4. But, you will also need a couple of?adapters. SMA to whatever termination / connector type you have on your antenna?system already.?PS: I also highly

For that use case I would recommend the H4. It has the larger screen that makes it a bit easier to use stand-alone, and has a full set of features with any recent version of firmware.
