## Description

Seesii NanoVNA-H Vector Network Analyzer Kit, New Upgraded 50KHz-900MHz MF HF VHF UHF Antenna Analyzer with Shell : desertcart.in: Industrial & Scientific

Review: This little machine is fantastic. It does a heck of a LOT of measurements, although typically most purchasers will in all probability only use the SWR function. Pros, This doodabber does a heck of a lot. It is very comprehensive for such a dinky little package. As stated, most will be using the SWR meter function. Which it does admirably. But it also shows Smith charts, and shows a lot more that I don't yet understand fully and yet more I don't understand at all. I'm sure in time all will become clear as mud... So the colloquialism goes. Cons... Do NOT expect a manual! It comes with a list of menu functions. And if your an amateur Amateur radio enthusiast, you will likely NOT understand a single dang thing. I most certainly did not. It has a qr code to a extensive online manual which for the vast majority of the time, is well translated, but can be a little hard to follow (especially for the beginner, YouTube WILL be your friend in this). It NEEDS to be calibrated for every use. Which is a little time consuming. But worthwhile for it's utility. and you absolutely WILL NEED adapters for ANY kind of antenna plug (PL259, N type, BNC, and any other.) It is set up for SMA Type plugs. it comes with what you see which is two extensions cables, both are female to female SMA, A male/male connector and three calibration caps (OPEN, SHORT and LOAD, DO NOT LOSE THESE! they are required for calibration!) A few usb cables (C type for charging and a C to C cable). And finally a wee lil stylus and a 'guitar pick' style doodabber. These are obviously for screen interaction. Build quality: it's a sensitive lil gadget. lightweight, and a little 'plasticky'. But it's well enough made to do what it's intended to do and be robust enough. Although a degree of care should be taken when transporting it. I keep mine in it's box which has sufficed adequately thus far until I get a better option, perhaps a small pelican case. Overall: This gadget does what you will need it to do (meshtastic users, I'm looking at you!) And significantly more besides. I can certainly promise at least 75% of end user's will not utlilise its entire arsenal of tricks. It's compact and very portable. And frankly I'm a little smitten with it. One cannot help but adore a well created and executed piece of kit. especially one as delightfully complicated as this one. 10/10 will measure SWR again.
Review: Pequeno em tamanho, mas gigante em funcionalidade. É uma das ferramentas mais importantes para um radioamador. Chegou direitinho, sem problemas. É simplesmente incrível. Vou poder regular e montar minhas próprias antenas a partir se agora! Vale muito o investimento. Achei que a tela seria pequena demais, mas é de fácil leitura e visualização, ainda mais se conectar no computador!

## Features

- Upgraded Nanovna-H HW3.6: SeeSii Nanovna-H Vector Network Analyzer is developed by Hugen. With latest 3.6 version,10KHz-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.

## 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.

*by D***K on 19 September 2025*

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.
