Hi Chackras, your amazon link leeds to a NanoVNA, not to version V2! -- DH1AKF

I fear this would be a rather tiny niche. Yes, APC7 is quite elegant and the gender-less design is neat. Unfortunately, to fully take advantage of this, your DUT probably needs to be APC7 as well. In

I seem to recall from the distant past, reading instructions for one of the early hobby vna devices about this. The software with the vna (mandatory pc to use it) could automatically readjust the

They may be reasonably priced, but don't count on them being any better. I have the female Rosenberger SMA kit and the load has a DC resistance of 48.82R. When you look at the specs, this should not

Those N to sma bulkhead items are $10 each on the link you gaveand the N end has 4 leaves for the central connector. Even allowing for two effectively in series, your results seem poor. Admittedly I

My (so far hapless) attempt to repackage my original 2.8" nanovna with N connectors (and later a 4" display, and still later my 2.8" SAA-2) lead me to purchase these panel-mount bulkhead adapters

That's very interesting, thanks!

Connector savers are your friend - I confess, though, that $20 in connector savers (or whatever a M-F thru costs) on a $50 instrument makes me wonder. Having a $50 VNA changes the whole mindset

How do you measure the return loss? Dave

Followup from my previous post.... I have just crushed my first female sma on my v2. The connector would not go very far so I took it off, before I started tightening the nut) and looked down the

Any one with bad return loss on port 2 (less than 20dB) at 1.5 Ghz ? <on7yi.pik973@...> wrote:

I see that nanoVNA-H, on its PCB v3.4, has an expansion port. Are there already examples of use of this port? I would like to use it for a bluetooth interface. Regards Piero, I0KPT

Dear all, I have several nanovnas (some lent to friends), a tinysa and a N-connector v2 on its way. I also have a Deepace Kc901s with N-connectors, an ancient (1990’s) home made spectrum analyser

@Shirley Dulcey KE1L I have seen China-made APC7-to-N adapters going for <USD20 online; i.e. about a third of the nanoVna's cost. You will need a minimum of one cable and two adapters to test a

Roger and Jim. I looked at Roger's png first, and that does explain why a dipole radiates and a transmission line does not. Will dig into Jim's antenna book when I have a chance. Many thanks for the

Michael, Please tell this newbee what indicates that the dynamic range is good. Thanks

The load of nanoVNA-H4 is designed according to 6GHz that S11 is better than -30dB. We can guarantee that S11 is better than -40dB at 1GHz. The 51 ohm resistor is matched in the laboratory, and we

I took an excerpt from a textbook on this subject for you that answers your question. Here is a link... https://i.postimg.cc/wM2mVtSS/Maxwell.png Roger

Takes a bit to think of your Yagi antenna as a 50 to 377 Ohm impedance transformer. And if you are building Stealth aircraft, you want them to look like 377, not 50 Ohm dummy loads! Kent WA5VJB
