Review: Great SWR for the money - I have read a little on these devices over the past few months, and decided that for ham radio use, if they worked as well as people seemed to think, the small size, internal battery etc. would make it ideal for field antenna work. I really wasn't expecting that much at this price. However, it arrived in a nice looking box with fitted internal compartments for cables, connectors etc. My first quick play with it impressed me. I was suspicious about using a square-wave and using harmonics for the higher ranges, but if you forgive the reduced measurement range, that actually works pretty well. Not as well as my bench VNA, but that cost just a tiny bit more. The biggest potential problem is the number of sample points. Being fixed at 101 points is rather limiting for wide-band scans. That said, its not that usual outside of microwave use that wide bandwidth scans are used/useful. If you really need that, there is software available (free) for Windows and Mac to control the nanoVNA, and with the ability to split the range into some number (you decide - how long you want to wait) of segments, and scan each segment individually, merging the results into a single view. If I had to find fault, it would pretty much be with the external components: * A guitar pick is better than a finger on that little screen, but a stylus would be better. * There is only one 50ohm load, the proper calibration procedure requires two, although you *can* use just one. * The open and short calibration loads are identical once connected or an adapter fitted. Marking these 'O' and 'S' would be useful. * The box is too nice to toss away, but lacks space for additional adapters/connectors. All that said, I highly recommend this for anyone wanting a VNA for sub-microwave use and not requiring ultra-precision. If you have never used this sort of equipment before there is a somewhat steep learning curve, and most documentation is either at too high a level for a lot of people, and assuming lots of basic knowledge, or really too low level and created by people that are maybe not really grasping what they are doing. I expect that problem to resolve fairly quickly. As an antenna analyzer for ham radio use it blows most of those costing 10 or more times as much out of the water, and is useful for other things too (like tuning filters etc.).only using for SWR across multiple bands, but beats the price on buying multiple meters.
Review: Ham radio operator must have - This nano vna has been a great learning experience. Super helpful when building/checking antennas. It does a whole lot more but haven't ventured out to learn more of. Great item for the price.

## Features

- UPGRADED NANOVNA ANALYZER: SeeSii Nanovna-h4 Vector Network Analyzer is developed by Hugen. With the latest 4.4 version,9KHz-1.5GHz measure range,4.0 inch LCD touchscreen, mini and portable design. This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR. It is a very handy & smart analyzer for electronics engineers, amateur radio operators, or radio diy amateurs
- BUILT-IN MICRO-SD PORT & TIME DISPLAY: The latest antenna analyzer with a MicroSD card port, so you can save field test data or screens to a MicroSD card at any time, supporting up to 32GB memory card. (Not included in the package).In addition, different from the old version of NanoVNAs, the date and time can be customized, which is convenient for you to further record and save data. The default firmware main function is used for antenna performance measurement
- 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)
- Abundant Accessories: Equipped with 1x NanoVNA-H4(with 1950mA-h battery), 1x USB Type-C cable, 2 x 15cm SMA male to male RG316 RF cable, 1x SMA male calibration kit - OPEN,1x SMA male calibration kit - SHORT,1 x SMA male calibration kit - LOAD,1 x Touchscreen pen. It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration
- Reliable After-Sales Service:We provide professional technical support to keep you away from after-sales worries. If you are not satisfied with SeeSii Nanovna Vector Analyzer or have any other questions, please feel free to contact us. Our after-sales service experts will reply to your information as soon as possible, We will do our best to solve your problems, and you can purchase and experience with confidence

### ⭐⭐⭐⭐⭐ Great for checking antennas! You can't beat the price for what it can do!
*by M***P on March 21, 2025*

Great for checking your antenna SWR! I used this for a meshtastic node to ensure my antenna was a good match. It was simple to use (loads of YouTube videos!). There is much more it can do beyond what I know! I brought it to my Ham radio meeting and they were showing me a bunch of things. Great tool to learn more about antennas and test ones you build! Other devices will cost you loads of money...this works great for all the main things.
