NanoVNA-H Vector Network Analyzer

I use it for my hobby to make/tune HF/VHF/UHF antennas, HF baluns, ununs to measure SWR (it's nice to see a graph for entire band), insertion loss, reactance, Smith Chart and there is more parameters I didn't try/don't know about yet. But there are lots of good videos on youtube about how to use nanoVNA. Of course there are better much more expensive options for antenna tuning, but I'm on budget and it's excellent tool for the price. This unit does has some limitations: - microSD Card is a nice feature to save screenshots/data files, but I had problems with that. I returned first device because of 'Fail write' error (I tried different 16GB/32GB/128GB cards with no luck). I reordered nanoVNA again, and got the same error. But it looks like there is a solution I found in nanoVNA groups.io. This device does not support newer SD cards. So I found an older slow 16GB SD card, formatted in FAT32 on Windows, inserted SD card in device powered off, powered on device and it looks like it started to work with SD card. I tried the same card before and it didn't work. Not sure maybe it's because originally I inserted the card with device powered on or it had some format issues, but now it finally started to work. To be on safe side I would power off nanoVNA before inserting/ejecting the card. - Only 100 points of measure, so if I set entire 3.5-30MHz band device has a step about 250kHz that is not enough to tune multiband antenna to exact frequency on each ham band. Also device must be re-calibrated for each new band range that is not very convenient. However a good thing that several bands can be saved as a preset, so it's manageable. - Small TFT screen is okay for me, however it's hard to read data in a sunny day, so not the best option for outside. Also sometimes graph covers text, so text is unreadable. - Questionable reliability. It's packaged well and has nice cables, but it's not built like a tank. It's more for indoor use. If I had unlimited budget for my hobby I would get RigExpert for outside use or considered more expensive nanoVNA model with 400 points of measurement and probably bigger screen. But, for the price this model is a way to go for me. It does work and helps me a lot. Overall excellent value.

This is a great device! The overall functionality and use is outstanding. The many options are astounding. The only difference I would do is get one with a larger display than this one, but this works fantastic and is that a great price point.

I didn’t want to spend hundreds of dollars for an antenna analyzer that I might use a few times in my entire life. This was inexpensive and it works fine. It seems like it would be very complicated and difficult to use, but there are lots of videos on YouTube that show how to use it, and if you just follow the steps, it works fine and is not difficult at all.

I'll preface my review with my job title as engineering technician in a UL test lab for an electric motor company. Why does this matter? I have access to calibrated instruments. Having a brain to use them is another story but I assure you I'm only half as stupid as I look. I bought this because I'm getting into radio and wanted to build antennas for my helium miner and other projects down the road. My review is based solely on use for checking antennas resonance, impedance, and SWR. The "load" for me was actually 51 ohms basically on the dot. Probably not a huge deal in the grand scheme. Its going to be close enough given you understand what you're doing with this thing. The little jumpers claim they're "high quality cable" right on the insulation so it must be true right? well they are something I would probably toss from this kit. The unit itself appears to work fairly well. It believe it will get you within spitting distance of real world ideal. its also useful in the demonstration of how objects around your antenna affect its characteristics. It does however require you to know when its lying to you and that means weeding through some incorrect information thats out there in the form of "tutorials". There seems to have been a few different iterations of this thing and not all of what you see will line up with the one you get. All of this is to say, this device trades reliability and simplicity for low cost and use of your brain power.

Reçu le colis a 19:00. Livré comme indiqué c.a.d aujourd'hui. Je n'ai pas encore testé le nanovna, il a été livré en Bonne condition, il ne testé plus qu'a effectué Les tests. En date du 7 février(2026) l'appareil semble bien fonctionne.

Muy buena compra y buen producto per se me hace complicado

Dentro da expectativa.

La batería por más que la cargues no dura la carga, Un pigtel se desoldo super rápido, no retiene carga, de ahí en fuera es bueno el funcionamiento
