Hello Francesco, hi everyone,
I bought it some weeks ago, in Italy. I asked for several quotations, so I can give you all the info.
I will write to you as soon as possible with the details, but please remind me (write directly to my address) if time passes.... .
Thanks

As I see some friends are giving details here, and as I found a couple of minutes free, here is the list of the shops in Italy where I found it and asked for quotations.
Radiofrequenza shop
Radio-line
DAE
HamRadioShop.
You can check the current prices on the shops' Web sites.
Bye
Giorgio

Because its screen dimensions ?

Because its screen dimensions ?

Outside, with daylight it will be very difficult to read the screen even if it is larger. It's a hassle to go outside.

Think that with a *much cheaper* NanoVNA, combined with software like nanaovna-saver, measurements will be much easier and more comfortable. Even from the station (close to the Tx), you can neutralize the length of the line between this point and the antenna thanks to the calibration.

It is true that you will then need a PC near the Tx to control the Nano-VNA box through a USB link. I have three somewhat complicated HF antennas (see QRZ.com); I always measure my antennas like this with a NanoVNA-F and my PC.

Hi Fran?ois,
I already own a Nano VNA Pus 4, but I want the bigger screen of the.
Further, I like the ergonomics of the SV4401A and its more solid N connectors.

Francesco, I purchased mine from a vendor on E-Bay in China. My F-V2 had just died and was thinking about buying a replacement. I had already seen reviews of this model and decided to give it a go. I was shocked that I received mine in about 10 days. It arrived in near perfect condition.

The firmware is pretty good but not 100% stable. I'm seeing some strange issues with reading when doing tight calibrations. For example, if I calibrate from 700-1100 meg and run a simple SWR sweep then the device gets into a weird state. I have to reset the calibration and load a known-working save file.

The functionality is really nice. The large screen is amazing and makes it really fun to use. It is very hefty however. If you want something that's pocketable then this definitely is NOT the device for you. It's large and heavy.

There are some UI issues that I don't like but they are workarounds for them. You can easily touch-drag markers anywhere on the screen if they get in the way, etc.

I hope the firmware becomes more stable in the short term. I'm debating about buying another F-V2 in the mean time for something pocketable. The firmware on the V2 was near perfect, at least for my needs.
