Just as a quick test, you can see early in the video the analysis of a rubber duck antenna. The device uses a rechargeable battery if you need to haul it up to an antenna tower, for example. NanoVNA is tiny but sweeps from 50 kHz to 900 MHz and has a touch screen. You can see one of the several videos he’s posted, below. bought one for about $50 and made a series of videos about it. Vector network analyzers - VNAs - haven’t had quite the same proliferation, but NanoVNA may change that. Now you can get scopes of various sizes and capabilities on nearly any budget. But after playing with it a bit, I think I can get at all the features I need after understanding the menu system.īTW the UI likely is a ripoff of some other UI, anyone who had HP or Tek or some other equipment and could say what the UI is a ripoff of, or perhaps it really is its own? Chances of me getting access to a laboratory VNA is quite low.There was a time when oscilloscopes were big and expensive. antenna analyzer) which makes a lot of the UI 'more buttons than absolutely needed' potentially making it more difficult to use than needed. I suspect a lot of people end up using these as 1-ported analyzers (i.e. I'd even go as far to say I'm happy with the crap clone, but mainly because I know I'll never afford a laboratory VNA (and spectrum analyzer as well). After I started playing with it, I concluded it's a pivotal piece of equipment on my tool bench along with my scopes and multimeters, and I think it's even more useful than the spectrum analyzer I'd like to get at some point. After hearing about a long time radio engineer talk about it over the radio, I ended up getting one as I needed an antenna analyzer anyway. I have a cheap clone of the NanoVNA-H (2.8').
