Measuring balanced antenna feeds with the nano is easy if it is not connected to anything and well decoupled from "ground". It would be nice to remove the influence of connecting a USB cable to a PC s

The first question that comes to mind is about accessibility to the Yagi to coax connection. I'm guessing, from your question, that it might be tough. If it isn't, disconnect it and take open-short-lo

Thank you David! This is a great resource. Funds sent.

Thank you!

Yes. I agree, R&S has published some very good information. My current questions revolve, very specifically, around fixturing and calibration for measuring "soft" ferrites, of which there is much less

I have a Copper Mountain VNA in my lab at work, so I will probably try to get some generic advice from them next week, without mentioning that it's really for use with a nanoVNA at home.

Single turn. Tolerance is a good note, but my readings are consistently less than half the specified value. Unfortunately, Fair-Rite is the only company who has written anything about how they measure

I agree with Jim Lux. Holding the VNA in your hand is both simple and probably the most representative of the performance with an HT. In the olden days, the German VDE 0871 testing standard used a sal

The parts I'm currently playing with are all Laird ( formerly Steward) 28 alloy, with the Z peaking in the 100-200 MHz region. The data I'm referencing is from their data sheets. I'll read through Jim

I having fits trying to measure lossy "soft" ferrites against the manufacturers curves. Over the range 1 to 300 MHz, I'm not even getting close, looking at either S11 into a short or S21. I've tried a

I agree completely Jim. Put the antenna directly on the nano and hold it in your hand the same way you would the HT. As a career EMC/EMI/RF engineer, I can attest to getting WAY too wrapped around the

Tonight NanoVNA Saver started crashing a few seconds after I connect to the first gen NanoVNA I've been using for a long time. The program finds the serial port, and is stable until I connect. It says

Using your numbers Lou, I would not call a 20dB reduction in E-field "very poorly as a shield". The most difficult part of using any spray is getting it in to tight corners. I''ve done "touch up" on c

Can the boards be purchased without components? I'd love to have a dozen of them on the shelf waiting for my next adapter need. Thanks, Brent, AB1LF

The second one is pretty much what I was thinking of. Apparently he is making the Gerbers available.

Does anyone know of an SMA equivalent to this board? I expect it would be an order of magnitude more expensive, but u.fl connectors are only expected to live through <10 insertion/removal cycles. I am

Do you have a PayPal account? Brent, AB1LF

If you don't mind a bit of home brewing; Mini Circuits has lots of surface mount pre-amps dirt cheap (<$3), such as: https://www.minicircuits.com/WebStore/dashboard.html?model=GALI-74%2B The only thin

I may not understand the question but, between the S11 SWR and Smith Chart displays, the nano comes from the factory with antenna analyzer capability. Were you looking for something else?
