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...

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

Thanks for that. Had the same problem. Now cleared

That could be worth trying. Maybe you have a ferrite core on hand and could make your own balun. I have used my NanoVNA to check for resonances in a "random length" long wire antenna, and it seemed to

I don't think any nanovna "V1" can work with good accuracy above 900 Mhz, whatever "flavor". For all my measurements above 300 Mhz, I use another VNA offering a much better dynamic range. A nanovna "V
