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 | 4.7 out of 5 stars 585 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/71k1QLI+JTL.jpg) ![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 2](https://m.media-amazon.com/images/I/812XytXe6kL.jpg) ![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 3](https://m.media-amazon.com/images/I/81a-z2cL5cL.jpg) ![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 4](https://m.media-amazon.com/images/I/81EkeOn67HL.jpg) ![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 5](https://m.media-amazon.com/images/I/71eO988uDAL.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 ### ⭐⭐⭐⭐⭐ Review *by D***K on September 19, 2025* ### ⭐⭐⭐⭐⭐ Review *by J***S on February 1, 2026* ### ⭐⭐⭐⭐⭐ Review *by P***M on March 26, 2026* ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/171114193-seesii-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz](https://www.desertcart.hr/products/171114193-seesii-nanovna-h-vector-network-analyzer-upgraded-hw3-7-9khz) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
