Review: Super amazing! - This thing is great! It's sooo handy and works like a charm once I learned how to use it. I use it mostly to measure SWR for the antennas I build. It can do so much more though, it's amazing! I got it on sale too for a lot lower price and was super happy about that. Worth the money and helps with many situations. Holds a charge for a good while and doesn't take long to measure an antenna once saved recalls are in it. Easy enough to use for SWR and not too hard to learn other measuring methods. YouTube is your friend. :)
Review: More than advertised! - Fortunately there are a ton of videos on Youtube to figure out how to use this device. This thing has more capability than I anticipated! Clear quality, the enlarged size really helps with my older vision. Quality of the product is great, feels good! They suggest that I say something about the ease of use...understand that this is a complicated piece of tech. The good thing about it as the larger and most updated version, some of the complication can be taken out. Please look at a bunch of videos on this and learn with it in your hands! Don't hesitate to purchase it. There is a ton of bang for the buck.

- IMPROVED FREQUENCY ALGORITHM: The Vector Network Analyzer can use the old 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 of dynamics, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics. Great for troubleshooting antennas and improving performance
- PC CONNECTION & TX/RX FUNCTION: The VNA analyzer uses PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software. In addition, the default firmware is mainly used for antenna performance measurement. The TX/RX method can measure the complete S11/S21 parameters (need to manually replace the transceiver port wiring)

### ⭐⭐⭐⭐⭐ Amazing and Compact Analyzer!
*by H***X on November 9, 2025*

You'll have to watch YouTube videos to learn how it functions and how to appreciate its versatility, because the single sheet of instructions is practically worthless. But it has all of the connections/components/attachments for the analyzer that most ham radio operators will generally need. As an Extra class operator this NanoVNA handles most all of the measurements I need for daily ham activities for a fraction of the costs of other equipment.
