NanoVNA-H4 Option
Features:
This Nano VNA is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld, stand-alone with 4-inch LCD display, portable with 1950mAh battery powered or USB powered.
The improved frequency algorithm 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.
The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring
Using PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software
The metal shield is designed to reduce the external interference and improve the measurement accuracy.

The nanovna arrived quickly, and in good shape, have only tried it a little but seems to works good. I did a swr test on an antenna and it was perfect.

Excellent! With the (almost latest) firmware (1 version back, from february and now it’s june).
I flash the latest from github – hugen79 – nanovna-h.
I have already checked one antenna. More are waiting in line 🙂
Very fast shipping (from shipping to delivery, 10 days to greece! ).

Okay, guys and girls, I have to brag about something to you! This VNA is simply a miracle of technology, seriously! It measures everything like crazy, from impedance to cable losses, all with incredible precision and speed. The interface is super intuitive, even for an amateur like me, so using it is a pure pleasure. And most importantly – the results are always reliable, which saves a lot of time and nerves!

Great, I am very satisfied. For this price, it’s worth it for everyone who plays with RF and not only. 200zł for VNA is like free. You know – it’s not R&S or Keysight, but it works surprisingly well. I am attaching the measurement of the quartz filter for IF 45MHz.

After searching among many, I found this one, which is the NanoVNA-H4 with a 4-inch screen, original Zeenko model ZN401, it comes with firmware version 1. 2.43 and as accessories two cables with SMA female/female connectors, all three calibration connectors, one between two SMA, a pen for the screen, and everything in a very nice and well-packaged box to prevent damage. Everything arrived well and quite quickly, works perfectly, and the device has a very good finish. The quality/price ratio couldn’t be better, I’m already using it and I have no negative comments to make, I recommend it to everyone.

Excellent, everything is up to date and works perfectly. The operation is intuitive and very simple. I optimized an ADSB antenna with it without much effort, just by improving the position +90km.

Cheap and functional. Ideal for testing antennas for the Meshcore network, and any others. Ideally, it should have a slot in the case to store calibration patterns, but…

Having seen similar units at other online stores for far beyond what i paid here – i’m extremely happy with this unit. Measures swr and cable loss perfectly. Plenty more to learn.

As described, well packaged and fast delivery. It works very well for antenna tuning which is why i purchased it. Plenty of youtube videos to get you started with calibration etc. A big thanks to the vendor for a faultless transaction.

The description was accurate. The item arrived safely. I haven’t tried all it’s functions as i do not know what half of it is. I got it for swr readings. Online videos showed how to set that up and turn off a lot of the other stuff . It works great for it.
