Review: Excellent Vector Network Analyzer – Perfect for Antenna Testing - I purchased the AURSINC Upgraded NanoVNA-H4 (Latest V4.4) to test some antennas I was building, including EFHW, linked EFHW, and dipole designs. I’m very happy with this product. It’s accurate, easy to use, and the 4" touch screen makes navigating measurements a breeze. *Note* I did go back and forth with buying the smaller screen version or even the next version up, but the VNA-H4 screen size is nicer than the small and I really don't need the features of the next version up or the added cost. Having also used AURSINC’s TinySA Ultra, I can confidently say that AURSINC and SEESII are the only vendors I trust on desertcart for this kind of precision test equipment. The NanoVNA-H4 worked great for measuring SWR, S-parameters, phase, delay, and Smith charts on my antennas. It helped me verify and optimize my antenna setups with my Yaesu FT-891 radio. Overall, I’m very satisfied and would definitely buy more products from this vendor in the future. 📐 Key Features: Frequency range: 9 kHz – 1.5 GHz (HF, VHF, UHF) 4" color touch screen for intuitive control Measures S-parameters, SWR, phase, delay, and Smith charts Compact, portable, and reliable for field or bench use Ideal for ham radio antenna testing and tuning ⚠️ Disclaimer: This review reflects my personal experience and is provided for informational purposes only.

Review: Inexpensive With Plenty of Capability - I am very happy with this after having used it extensively for the last couple of weeks. A perk of my profession is that I get to use really expensive and capable test equipment at work but I wanted some of that capability for my hobby projects. That said I went into this purchase not expecting professional quality gear. My expectation was for hobby equipment and I feel like this product fulfills that expectation quite well. There is plenty out on the web regarding what this does and does not do, so I won't rehash that here. I will say that there are many firmware available for this and some do different things, or do some of the same things differently. In any case, you will likely want to update the firmware on this or try one of the others. It is quite easy to do. This particular unit came in a plastic case with a couple of cables, an SMA F to F barrel, and the terminations for calibration. A USB cable is also included along with a nice stylus, something that is absolutely a must for the operation of the touchscreen. Everything you need to get started is here except documentation. That's reasonable because any documentation will be specific to firmware and firmware changes often. So you'll get that yourself electronically and you'll likely want to watch some videos as well to get up to speed on the operation of it. The included plastic case might be ok for some, but I recommend you put this into some more robust storage when not in use. At this price what you are getting is somewhat delicate and exposed. That's fine for a reasonably clean bench. I've even used it with care in the field. Just know that this isn't something you're going to casually throw in the tool bag, you're going to want to protect this. So far I have enjoyed using this for a number of tasks including: sweep antennas, tune filters, tune antenna traps, measure inductors, measure capacitors, and so much experimentation with tuned circuits. Not only has it increased my productivity on my hobby bench, it's really helped me to learn some concepts and reinforce others. What a pleasure to be able to do that without worry because if I harm this thing in the process that's a whole lot different than playing around with my professional test equipment at work that costs tens of thousands of dollars. In conclusion, this is a nice inexpensive bit of kit that produces reasonable results for the hobbyist. I am quite pleased with it.

## Features

- UPGRADED NANOVNA ANALYZER: AURSINC NanoVNA-H4 Vector Network Analyzer by Hugen features the latest V4.4 firmware, a 9kHz–1.5GHz measurement range, and a 4.0-inch LCD touchscreen. The Antenna Analyzer provides outstanding performance for S-parameter testing, antenna resonance analysis and SWR evaluation with excellent vector network measurement capabilities. It is an efficient testing tool for electrical engineers, ham radio operators, antenna builders and radio DIY enthusiasts
- IMPROVED FREQUENCY ALGORITHM: The improved frequency algorithm of Nano VNA H4 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. Used it to check out new cable or antenna installations and to routinely adjust the RF tuner for optimum
- BUILT-IN MICRO-SD PORT & TDR FUNCTION: This antenna analyzer features a brand new panel and a new SD port for data storage, supporting up to 32GB memory cards (not included). Unlike older NanoVNA versions, it lets you customize the date and time for easier data recording. Added TDR functionality—widely used to quickly measure coaxial cable length and locate faults via impedance discontinuity calculations. The default firmware's main function is antenna performance measurement
- PC CONNECTION & ANDROID CONTROL: Using the PC software NanoVNASaver, the Nano VNA H4 antenna analyzer can connect to your device, extract data for display on a computer, and save it to Touchstone files. You can also export Touchstone (snp) files via the software for use in various radio design and simulation tools. With its TX/RX method, the analyzer measures complete S11 and S21 parameters. To obtain S12 and S22 parameters, you only need to manually rewire the transceiver ports
- WHAT'S INCLUDED: 1 x NanoVNA-H4 Host (built-in 1950mAh long-life battery), 1 x 4pcs SMA Male Calibration Kit (open/short/load + SMA female-to-female connector, for precise calibration), 2 x 6.3-inch (16cm) SMA Male-to-Male RG174 RF Cables, 1 x USB Type-C Data Cable, 1 x Type-C to Type-C Cable, 1 x Lanyard (with integrated stylus), 1 x Extra Stylus Pen, 1 x User Manual. It's a great antenna analyzer for your ham station—easy setup, no complex calibration
- RELIABLE AFTER-SALES & TECH SUPPORT: We offer pro technical support for your AURSINC NanoVNA-H4 (usage & troubleshooting) to ease post-purchase worries. If you're unsatisfied with the antenna analyzer or run into any problems, don't hesitate to reach out. Our dedicated after-sales service experts will promptly respond.

### ⭐⭐⭐⭐⭐ Great tool for Hams
*by B***R on November 22, 2025*

Great little tool. Helped me troubleshoot issues I had with a mobile setup and get my SWR down to 1.4. Price is great compared to other VNAs, build quality is decent, only downside is the documentation it comes with is pretty lacking and has to rely on YouTube videos
