    The NanoVNA provides alot of value in a tiny size. It has features that go beyond what we need most of the time with amateur radio, so there is a bit more complexity to the unit. With that said, if you have a bit of patiences you can learn how to use this for your antenna building.

    I assume it only does S11...hmmm nope! Does S21 also!!

    Never mind:)

    Definitely pretty, and cheap!

    Yes, it measures both amplitude and phase and measures both S11 and S21 so it really is a two port VNA.

    I bought the F version with the larger screen, metal box, cables and cal kit. I like it and I’m glad I got the larger screen. I’m posting my experiences with it in the General Tech forum.

    My mfj-259b will be collecting dust now.

    I really like my NanoVNAs including the larger F version I received recently. But I still expect to get plenty of use out of my antenna analyzers as they're a lot easier to use in the field for many antenna adjustment and measurement tasks. They have the right connectors for use with most of my ham antennas, they don't need calibration before a measurement session, they're much easier to read with large text and analog meters and in the case of my MFJ analyzer it's much quicker to do fast frequency sweeps with the twist of a knob than it is to program in start and stop frequencies with the NanoVNAs.

    Sure there are many great things about these NanoVNAs and if you don't already have an antenna analyzer it can be a great way to go but IMO they're not nearly as convenient for field use and things like tower top work as a dedicated antenna analyzer.

    The dedicated units are also very rugged.
