Sci fi level status. I love it! It does take some getting use to and is not as easier as the old school ones but just has so many more capailities and is very good for the entry level hams. Plus its not as nearly expensive as the other two big names. Yes... i do have others. This one is compact and portable with spot on accuracy. Only downside is the open, short, and closed calibration situation..but just make sure to save that parameter profile for the band you will be measuring and you wont need to do it again. Thank you so much i will definitely buy another one. Review: Great instrument to fine tune self made antennas and coils. - Amazing too for an amazing price. I finally can check the swr of my antenna and optimize it. Perfect too for ham radio enthusiasts that like to thinker arround. ## Features - Upgraded Nanovna-H HW3.7: SeeSii Nanovna-H Vector Network Analyzer is developed by Hugen. With latest 3.7 version,9KHz-1.5GHz measure range,2.8 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 mini handy & smart analyzer for electronics engineer, amateur radio operators or radio diy amateurs - Improved Frequency Algorithm: The enhanced frequency algorithm uses the odd harmonic extension of the si5351, supporting measurements up to 1.5GHz. The metal shield reduces external interference, improving accuracy. The si5351 direct output offers 70dB dynamic range (50K-300MHz), 60dB (300M-900MHz), and 40dB (900M-1.5GHz). The default firmware supports antenna performance measurement - Multi TX/RX Function: 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) - Android and PC Software Control: The NanoVNA analyzer uses NanoVNASaver software, which connects to the device, extracts data, and saves it in Touchstone format for display on a computer - Built-in Micro-SD Port & Time Display: The lastest antenna analyzer with MicroSD card port,so you can save field test data or screens to a MicroSD card at any time,support up to 32GB memory card. (Not include in the pacakge).In addition, different from old version 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 - Abundant Accessories: Come with 1x NanoVNA-H host, 2x 30cm SMA Male to Male RG174 RF Cable, 1x SMA Female to Female Connector,1x SMA SHORT,OPEN &LOAD simple calibration kit,1x USB Type-C Data Cable, 1 x USB-C to USB-C Line, 1x Lanyard and touch plectrum. All the accessories are packaged in a sophisticated box.This is nice vna analyzer for your own use or as a gift for your friend ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 605 Reviews | ## Images ![SEESII Nanovna-H Vector Network Analyzer,Upgraded HW3.7 9KHz-1.5GHz MF HF VHF UHF Antenna Analyzer, Measuring S Parameters, Voltage Standing Wave Ratio,Phase,Delay,Smith Chart,Support Data Storage - Image 1](https://m.media-amazon.com/images/I/71hBfM5XkiL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: What does it mean ”if you need to get s12/s22 curve, please exchange the tx/rx port manually”? is it easy to do?** A: To change the TX/RX port simply unscrew the connection cable from the upper port on the NanoVNA and reconnect it to the lower port. **Q: Will the unit be the 3.4 if i order it now?** A: Yes, it is 3.4 version, if you order it now **Q: I read in description "900 mhz - enable extended firmware." what does this mean? does it cost extra?** A: As I understand it, you can extend the range of the device by a firmware update. But there is a resulting decrease in performance. It’s a free update if you so choose. Wayne N4EYZ **Q: What connection type does the battery charger use?** A: This is an add-on to the other answers that may prevent damage. Quote from specs. on this product page: "maximum charging current 0.8A" In other words, this may get damaged if more than a 1 amp USB charger is used. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buy it, trust me dont wait *by D***K on September 19, 2025* Works really well.

I finally can check the swr of my antenna and optimize it. Perfect too for ham radio enthusiasts that like to thinker arround. ### ⭐⭐⭐⭐ Great test equipment for low cost *by R***S on June 20, 2026* I'm very happy with mine. I used it to analyze ham radio antennas but looking forward to using it for tuning filters and other uses. It's also a good RF generator, if you set it to zero span. If you set it a very small span, you would get FM modulation on the RF. By proper manipulation of the menus, you can view reflection coefficient, Smith chart S11 and SWR at the same time - very handy for adjusting antennas or antenna tuners. If it had a manual or a link to an online manual, I would have given it 5 stars. The menu system is clear enough that I was able to stumble through without a manual; there are good tutorials on U-tube. Other reviewers claimed problems with the battery life; so far mine is performing well. The screen is small but that's in the description. I use mine with reading glasses so I read the screen. They include a stylus (and a guitar pick) to use the touchscreen menus - it's not hard using the stylus. The include lots of RF goodies with it, as advertised, SMA jumper leads, adapters, calibration set (very important). I also bought a few more adapters on Amazon so I can hook up to more antennas. Back in the day, a VNA cost about $15 000 so the price is a true bargain ## Frequently Bought Together - SEESII Nanovna-H Vector Network Analyzer,Upgraded HW3.6 10KHz-1.5GHz MF HF VHF UHF Antenna Analyzer, Measuring S Parameters, Voltage Standing Wave Ratio,Phase,Delay,Smith Chart,Support Data Storage - DHT Electronics Handheld Antenna Cable SMA Male to UHF SO-239 Female Connectors 6'' Pack of 2 for Amplifier - onelinkmore SMA to UHF RF Coaxial Extension Converter CB Connector kit SMA PL259 SO239 VHF Crimp Coax Adapter for Ham Radio Antenna Walkie Talkie Radio Pack of 4 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/171114193-seesii-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz](https://www.desertcart.com.ar/products/171114193-seesii-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-19*
