If it already Has the firmware needed for tunning above 1.5GHz, that would be nice... I know the V2 or LiteVNA are better for those frequencies, but this should get me started...

Yes. It may already have the needed firmware. But note that the extended range above 900MHz has a much lower dynamic range. If you really need to do a lot of work at above 1GHz, you should consider ge

Hey, i know its been a while, but would that firmware work for this unit? (To extend its range a bit...) https://vi.aliexpress.com/item/1005006338561014.html Hopefully links are fine...

Hi again. Can you help me with this: I have set stimulus for resonance, between a set of frequencies, and it works ok, but, I am getting confused how to save it, after switching of !

Thanks. In some instances I may need a standalone, like tuning an antenna, traps , end z etc . Much appreciated

You should not need a special driver for Windows 10 to use this nanovna with NanoVNA-Saver or NanoVNA-app software on your computer. Windows normally will automatically load a default driver that work

Can someone point me to the proper windows 10 software and driver to this version, please ? And, do I have the latest firmware version ? Thanks NanoVNA-H HW 3.5_LS_MS Based on DISLord edy555 Version 1

Carsten, my experience is all antennas, even those off the shelf one, need some finetuning. 1. Tuning - I would recommend the minimal height for tuning purposes is 3-4m over the ground at the end of t

@igor-m The summerhouse is in Sweden (900m2 Lot) , near Halmstad (outskirt of city). There can be both thunder & high winds (30m/s, when ugly) I was thinking of hammering 2 x 3M groundrods down , and

@Carsten: Lightning and Static: in the EFHW antenna with the transformer the antenna wire itself is grounded through the secondary and the coax via primary windings (a short for static). Your system h

there were NEVER any v2plus4 clones.. so you will get a genuine one (i would now maybe buy a lite vna that goes up to over 6ghz but is a similar design as the vna v2 or v2plus4) the nanovna v2 has an

@All Thank you for the valuable input. @Roger , for the nice links to schematic & More specific groups. @gfmucci for the "Static warning" @Jim & Zack for the "Don't connect the FT-991A directly to the

And as far as static goes: Remember that any coax is, by design, low loss and can store a sizable amount of energy as a cylindrical capacitor. So, I always make a practice of "shorting" any coax I con

I have been really careful about estimating power out of an amp. I have an HP 435B power meter with an 8484A head. Maximum power to the head is supposed to be 10 microwatts (-20 dBm). I carefully calc

The second most likely is "transmitting into it", or, more properly, making S21 measurements on a small amplifier that has output power bigger than the VNA can take. That 20dB gain block, driven with

"What is the most likely way that beginners kill their VNA ?" Static buildup especially in dry climates. I had one DOA and the vendor said static buildup killed it.

Carsten, Here is a link to the manufacturers Web site for your NanoVNA 2 Plus 4 Firmware, instruction manuals and PC software available there. https://nanorfe.com/nanovna-v2.html There are two groups
