Features:

This Nano VNA is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld, stand-alone with 4-inch LCD display, portable with 1950mAh battery powered or USB powered.
The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics.
The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring
Using PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software
The metal shield is designed to reduce the external interference and improve the measurement accuracy.

  1. Jez Girl –

    I bought these to check my antenna system and coax , works just as good as the $1000 units , you just need a step or 2 more to calibrate it first. Well worth the money

    I havecbeen building my own antennas for decades. Without this tool, I only had my radio and SWR meter. Now I know what is right and wrong and it makes corrections when tunning easier.

    I use it for several things, antenna analyzing, finding values of unknown capacitance and inductor values, testing coax…etc.
    It works great.

    Actually matches current specs..

    H4 is great but this model was shipped with a dead battery, so sent it back.

    This is my second NanoVNA, the first one is a small form factor, and is difficult to read in the field. This one is a big step up and very useful. The cost was also reasonable for what you get. Highly recommended!

    What do I like? I like the ability of the device to measure RF S11 (reflection), S21 (forward gain), and related parameters over a wide frequency range at a very attractive price. I like the fact that there is free software available such as Nanovna Saver, which enhances the measurement capabilities and utility of the device. So far, I have only done some calibrations, VSWR measurements on an antenna, and started using Nanovna Saver. All results were reasonable. I have nothing negative to report. I have not attempted to measure its accuracy in any detail. I have used network analyzers in the past, and find the Nanovna easy to use. The menu navigation sheet is very useful and helpful. Watching on line videos on the Nanovna prior to receiving the device was helpful also.

    The construction of the device seems to be similar to that of a cell phone, and it is probably more fragile than that.

    This helped me determine the problem with a second-hand 2meter antenna. I also found a separate problem in a not visibly damaged cable. There is a menu guide included but for detailed instructions YouTube videos are the best thing.

  9. Adam M. Czepiel –

    It works..large learning curve…I’m glad I bought it to try it..

    Stick to the much better real stuff..from name brands…lot more money but much more rugged..

    I 50% recommend

    I just picked up a new HF multiband antenna and needed something better than an SWR meter to tune it with. This did it. It’s a bit of a learning curve. I downloaded the software for it and that helped. I can save a shot of the results of a test and compare it to the next test. it really helped with the antenna build. The spectrum scope will show the performance of the antenna in real time on all the bands. Pretty darn slick. I’d give it 5 stars but the learning curve took it to 4.
