NanoVNA-F V3 1MHz-6GHz Vector Network Analyzer,4.3Inch HF VHF UHF SHF Antenna Analyzer Built-in 4500mAh Battery,Measuring S Parameter,Voltage SWR,Phase,Delay,Smith Chart,RTC Real-time,801 Scan Points

Has more features than I need but works well for checking VSWR on end-fed/multi-band antennas.

It made checking, making, and tuning some antennas MUCH easier. You can do it with a few second test, without needing to use a separate radio, and a lot of messing around. I also tested several coax segments (found one bad one!). There are lots of videos you can search for that demonstrate how to use it.

Nice tool, touchscreen calibration is awful, also the firmware is buggy, I have to connect it via USB and start the calibration by serial commands since it's not possible to do it by the menu.

Words can't describe how good this vna is. Great price. Wonderful tool.

My first analyzer the key board had issues. Amazon sent me a replacement and it works as expected.

Great tool, works as intended and user friendly.

Included everything needed to get started and easy to use

Compared to my 2" screen with an older firmware and slower processor, this nVNA-F v2 is incredible! Easily links to PC running Windows 10. So many types of software available now to connect with it. This particular package is amazing! Comes with a hard shell case with foam inlay, 2x M-M SMA cables, stylus, Open/Short/Load calibration connectors AND gender changers as well as angle adapters! Seriously everything to get you started! Is it worth the extra $$? I would say for what it comes it and what it is, absolutely! The aluminum housing is superb quality and screen appears to be anti-glare!
