LibreVna

[Pixelx]

Hi,

what do you think about libreVna, is it worth the price or are there any problems with it?
Somewhere I saw a video on YT that the problems were with the drift temperature and it was decalibrating, but it was a video added from 3 years ago.
What is your experience with this VNA?
I will add that I am not interested in nanoVna. I'm looking for something more professional for good money.

I found the same libreVna, but in a different housing, one with a larger radiator. I wonder if it is officially installed this way or if someone buys an ordinary LibreVna and then installs such a radiator. I am concerned about calibration and measurement accuracy if someone does it on their own and changes enclousure that are not from the target design.

Do you have any videos on tuning the antenna with this VNA?

where is the best place to buy LibreVna apart from aliexpress?

And is it possible to save a touchstone file?

Performances of LibreVNA are pretty much the same as LiteVNA, which cost much less and have a display also.
The cons of LiteVNA is that is not full two ports VNA. You can do S11, S21, S12, but cannot do S22, so you have to swap the cables for this measurement.
Both VNAs have lower dynamic range for frequencies between 3GHz and 6GHz (~50dB).

Thanks for your reply.
I will stay with libreVna because the application for it and the firmware are still being developed and I like it better and I am not limited to S22.

However, I am wondering about the remaining questions that I asked in post 1

What is this SeeSii name?
Some VNAs are without this inscription. Does this change anything?

Are there any ready-made designs as cooling pads for LibreVna?
