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.

Awesome VNA meter.
Should have bought this a long time ago. I recently purchased a cheaper version of this without the case. For a few bucks more. I suggest you buy this one with the case and the ability to take a microSD card.Item came well packaged and it works straight out of the box. There are a numerous tutorials on YouTube on how to calibrate the meter. I suggest you watch them as it is pretty easy to do and take a a few minutes to do.This is just another tool to add to the ham box. It also a very useful tool to test out antenna to show you what band is the antenna is cut for and the SWR you're getting back to the radio. Don't solely rely on this. But it's a great tool to give you a baseline where the antenna "sweet spot" its at. I tested several HT antenna you can clearly see where the band or bands the antenna is at.Great and awesome tool for ham operators. Very well made and happy with the purchase.
