NanoVNA H4 Setup & Calibration

Today we will be setting up and calibrating our NanoVNA H4. Previously we did the firmware upgrade on the NanoVNA H4 which removed all of my previous settings and calibrations.
NanoVNA H4 Firmware Upgrade: • NanoVNA H4 Firmware Up...
NanoVNA H4 (Affiliate Link): amzn.to/3JIDGXD
SMA Calibration Kit for NanoVNA (Affiliate Link): amzn.to/43l1gCQ
Please note: It is necessary to rerun the calibration whenever a new frequency range has been selected. This is based on what I have read in the NanoVNA website and manual.

This is absolutely the BEST setup tutorial I've come across. 👍

[@courtneyproctor2691]

Agreed

[@carlosadrianob.blanco6521]

Thank you Matt for providing some directions on how to calibrate it. Greetings from Brazil. 73 from PY2QA 👏👏

[@FireRescue884]

Out frigging standing, exactly what I needed and easy to follow, great job 👍

[@johnnorth9355]

Excellent - I was wondering how to set mine up and now I know. Many thanks.

[@davidbardsley7760]

Thanks-you so much for the informative content. Your assistance was spot on, and near infinitely more useful than the included "structure map" LOL. Please don't misinterpret my tongue-in-check bard about the included documentation; The nanoVNA product line is clearly advertised as a "DIY" project, so the community to which you're contributing is greatly valued and appreciated. Again thank-you for the help.

[@BronxCowboy]

Thank for a cogent presentation! Thanks too for pointing out the dielectric as a way of distinguishing the calibration ccps

[@n3vanradio]

You are very welcome! Thank you for watching.

Between you previous video (NanoVNA H4 Firmware Upgrade) and this one, I'm ready to go. Great video. Easy to follow along step-by-step instructions No for an antenna testing party :) 73

Question: These Nano VNAs vary, in price, from $40-$50, to some in the $120-$140 range, up to the "Mini-1300," for $180. As far as I can tell, they all seem to have similar performance. The more expensive ones have larger displays, but that's about the only difference I can find. They all have a sweep function, measure R & jX, produce Smith charts, & measure VSWR. Frequency ranges are similar, and more than what I need (2m & 70cm). So, how is the $180 one better than the $40 model?

[@janiceemery2008]

Excellent video Matt, thank you for sharing.

[@n3vanradio]

Glad you enjoyed it!

[@wb1340]

Awesome video, thank you! I have been trying to figure out, on my own, how to change the way the nano displays swr.

[@leftcoastexploring1389]

great video thank you!

[@manuelcv9475]

Excellent explanation. Thank you

[@n3vanradio]

Glad it was helpful for you. Thanks!

[@chriswesley594]

The word you want is "dielectRic" - note the R. There is a word "diAlectic, but it means something entirely different. Thanks for the great video.

[@n3vanradio]

Hahaha I know my mistake over the years I picked up the "dialectic" term from a family member.

[@yugosuprihantopo9750]

nice

[@MrMeasureTwice]

Excellent walk-through! BTW, there is an R in dielectric (sounds like die-electric) - sorry, not being mean, I'm just one of those nit-pickin' goobers.

[@n3vanradio]

Good catch! Yes I was thinking of dialectic like the dialectic grease you put on spark plugs, etc.

[@MrMeasureTwice]

@@n3vanradio That's also with an r. 😟

[@muskrat1949]

How do I reset to default?

[@daviddyessii1126]

Can the Firmware be updated?

[@sarbog1]

S eleven ....huh? Isn't it port 1 to 1 ... meaning reflectance?

[@keathrhymer5449]

if isave how do i get back to what i saved just got the unti and the manual is like 80 pages

[@n3vanradio]

Hi Keath, to get your saved settings you should be able to go to Recall tab and have them show up. In an upcoming video you will see that when I tune an EFHW wire. Manual is extensive as this little device can do a lot! Thank you for watching.

[@tstorms68]

TY

[@n3vanradio]

You are welcome!

[@richardcallihan9746]

Is not the open cap's purpose, to shield the open port?

[@n3vanradio]

Correct!

[@Wally_GTO]

Mine got frozen 🥶 and it’s not moving 😩

[@n3vanradio]

Oh no! Frozen during or after the setup and calibration or the wheel that sometimes locks up?

[@Wally_GTO]

@@n3vanradio 1st time use tho. I turn it on then I was about to do the calibration and got frozen 🥶.

[@n3vanradio]

Hey Wally sorry for delay. If it is frozen then the case may be touching the screen due to faulty extrusion in manufacturing. Try to loosen the screws and it should work :)

[@thinklab4598]

It's dielectric not dialectic. I'm not a vernacular nazi normally, but considering you sound like an intelligent person I thought I should say something so in the future people do not underestimate your intelligence.

[@n3vanradio]

Thanks! It was how I always used to say it when I was working on my own cars with my father. But thank you for the correction :)

[@rosie9490]

Why do you keep saying dielectic?

[@n3vanradio]

Im sorry. It was a mistake on my part :)

[@wesmcfarland4106]

Great Video! Got a H4 still sitting in the box. Been so busy studying for Extra I haven't had time to play with it. Passed the Extra exam tonight and when I came home this video was waiting for me! I'll be watching for updates. K5WFD/AE ch

[@n3vanradio]

Congratulations on passing your Extra exam! I too am studying in the little spare time I have for the Extra as well. I am also studying morse code so i can add CW to my comms skill box. Thank you for watching and 73, Matt N3VAN
