If you have old V2Plus4 hardware, you can use my v1.0.69 or later firmware for it. I fix data exchange vs NanoVNA-App in it. PS new V2Plus4 devices change lcd module type and my firmware not work

Hello, I like to send thank you for the work you have dan before, I continun to use your software for my old NanoVNA. My best regards. Francesco *Sent:* Wednesday, November 03, 2021 at 9:55 AM *From:*

I'm afraid you're right it doesn't work with the V2plus4, I never had one so couldn't write, test and debug any comms to it. I gave up writing software for hardware I don't have quite some years ago

Hello, I use the NoanoVNA APP software on my old Nano but not work on the NANO V2+4 some help, please.

Actually it can if you connect a receiving antenna to port-2 (S21) with the antenna to measure on port-1 (S11) via a long piece of coax. Place the antennas far apart out in the open and rotate the

Don't expect more out of a VNA than it can deliver. It can help you design a good matching circuit at the feedpoint of the antenna. But it cannot help you measure the antenna's pattern or gain. 73,

Have no idea about par numbers but those are commonly available on Ali and Ebay. I got these: https://s.click.aliexpress.com/e/_ADBHGt

Good day to all the group. I have had my VNA fir a few years and really not done to much with it other then playing fir the first day or so. I had to build a antenna fir 915Mhz and I needed a little

Yes, was planning that as the next step, even without exact values of antenna, at least to try and get a better sense how CMC modifies impedance. I hope SimSmith has CMC as an element I can use. CMC

bbdowns, that is a neat solution. Can you provide part numbers for those male and female socket/plugs? Thanks, Roger

Thanks for the feedback. At this time I only measure up to 1.5 Ghz so I will use my Nanovna. Mike N2MS

If you are the owner of an nanovna and you do not need to test beyond 3GHz, I suggest you not to consider this. Its user interface is not as versatile and convenient as nanovna. The PC app that goes

Assuming that the transmission line is decoupled from the antenna (i.e. imagine the whole length is covered in absorber/ferrite), then the transmission line won't change the feed point impedance of

Here is another LOOOONG reply, appreciate all that are taking time to read and answer/offer explanation or add more questions :)

As a learning tool, I'd suggest you download and "play" with SimSmith: http://www.ae6ty.com/smith_charts.html Using coax, the antenna structure must be isolated from the feedline. This can be

Here is what nanoVNA sees AFTER the CNC (nano calibrated with length of coax, and then connected after the CNC) (image attached, not sure if it will show as embedded in the text though). Looking at

Actually, I'm not using OCFD in real sense, but concept is the same :) I did not want my question to "shift" toward antenna design and OCFD in particular, but to stay around "how to avoid impact on
