NanoVNA-F V2 4.3Inch Vector Network Analyzer 50KHz-3GHz with 5000mAh,Aluminum Case Touch Screen NanoVNA V2 Antenna Analyzer Shortwave HF VHF UHF SWR-Measuring S Parameters,Phase, Delay, Smith Chart

Construction is solid, good metal case. It came on a nice carrying case as well with all the accessories for calibration. A great device to learn about VNA and antenna+duplexer tuning. A must have to EE students too. If you deal with VHF/UHF/SHF antennas, you may need some more accessories such as PL259, SO239 and N adapters. The manual is very thorough and written in proper English, however it assumes you know VNA theory. After watching a few tutorials on YouTube I was able to use this VNA easily. The screen-touch feature sometimes fails (it's very small and not that precise), but you can use the side buttons to move the markers. Overall, for the price tag this is a very powerful VNA. I compared some results of antennas previously tested with Tektronics VNAs and results weren't too far off. One note thought, this product comes with a USB-to-USB-C adapter to charge it and you must use it. If you try to your own USB-C-to-USB-C cable it won't charge. The manufacturer confirmed to me it won't work charge with USB-C-to-USB-C (bummer, one more cable to carry around).

This review is for WellHome Innovation NanoVNA-F V2 This device seems to be using Sysjoint hardware and firmware (v0.5.0). From what I've read there are a lot substandard clones currently being made of this device, so buyer beware. I have only had the device for a few days but have had a chance to set the center frequency for a number of steps from the low to high end of the frequency band of this device while monitoring the port 1 output on a spectrum analyser and the output looks good. I found out about this device from a YouTube video by IMSAI Guy titled NanoVNA-F V2 Initial Look. The video is worth checking out. Documentation, firmware updates and PC software for this device can be found at www.sysjoint.com. This device is well built and seems to be functioning the way it should so i do believe it is a good buy.

I purchased this to replace my regular NanoVNA 4 which I put in my QRP field gear. This is a nice vna but it I wouldn't necessarily say it's better then the NanoVNA. It's better in some aspects but worse in others. Scans better but can't link it to a larger display (yet) and updates aren't as abundant.

I have it for a few days and it seems this thing is working. Can't say too much about it, the calibrating parts seems to be OK, the two pigtails as well. I could evaluate my antenna with it and tuned my home-made rf amplifier to the required band. (Used my own 20 dB attenuator on the output port for this! It is a separate item, did not come with the package!) Overall I'm satisfied with the VNA so far, although I only used it in the UHF range so far.

Large display easy to read! Overall excellent product!!

It does work fine, looks like the scan from my aa-600, but a learning curve to get there, bought it to check out a 1.2 gig antenna, and didn't get what I expected.. lots more to learn. Hopefully some of the bugs will come out with updates,..

Support is available which made me happy. I looked it over and was satisfied.

Works as advertised
