Having own the baby version of this tool. Again, it's not a hardcore, professional tool but more of a hobbyist. It is darn accurate and will put you in the spot where you need to know about your antenna and it's attachment points.
Being older it's really hard to read the screen on the baby NanoVNA. With this the screen is way way bigger and much easier to read. The battery last a lot longer too. Was able to do a comparison between the two with several of HT antennas I have here. All ranging from junk rubber ducky one to the standard one that Motorola supplied with when you buy a APX8000.
Both NanoVNA are dead on with each other so I know they both work on measuring the SWR, Smithz and reactance on the cables and antenna.
I'm not going to be writing a how to with this review as for anyone who buys this. You should know what it does, how to use it, and what you should expect from it. There are plenty of how to on using these devices.
Overall, this is one great device to measure your HT, mobile and base antenna. Is it better than the Comet, MFJ, or Rigeet? Not sure and I doubt it. But it's another tool you can add to the belt to double check and use to give you a reference point and baseline.
Great network analyzer and would recommend to anyone who wants to "tune" their HF or anything radio related.
