Review: Buy it, trust me dont wait - Works really well. 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: Best Value in Ham Radio Equipment - Incredible deal. Easy to calibrate and use. Provides a graphical depiction of SWR across an entire band - a must have for all ham radio antenna experimenters. You can now easily know your SWR and Impedance not just a specific frequency but across an band. I use an antenna switch to keep it connected simplifying the tuning of my SWR when switching bands before transmitting. Numerous you tube videos showing how to use it properly. High quality build and components. Love it!

## 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

## 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.

**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.

### ⭐⭐⭐⭐⭐ Very useful tool. Get one❗️
*by J***S on January 7, 2026*

Great tool for tuning and so much more. There's a learning curve but don't be intimidated. Once you figure it out, it delivers as much and more info than a Rig Experty AA-35 Zoom or an MFJ 259(x). I have them as well but the Namo VNA is just more info. Smith chart is a bonus.
