Frequency CoverageĪll three of the VNAs I’ve used claim to work up to 1.5GHz. All three have had problems and/or limitations. I’ve owned three “cheap” NanoVNAs I picked up from Amazon or eBay. Joe has a playlist dedicated to the NanoVNA and he seems to like the NanoVNA V2 Plus 4 also. Anywhere his opinion differs from mine, trust him rather than me. I’d recommend Joe Smith’s YouTube channel (no relation) for WAY more information than I’ll list here. There are people with much more informed opinions than mine. Historically, I just recommended one with a large screen (because these eyes aren’t getting any better), with no knowledge of the quality of the VNA itself. I’m not a metrologist, so I have basically no leg to stand on to recommend one device over another. Currently () that’s the NanoVNA V2 Plus4. If you don’t care about my reasons and just want to throw money at something you’re not likely to regret, get the original from the people doing the actual design work. tl,dr: I recommend the “NanoVNA V2 Plus4” from NanoRFE Since I started selling the Common Mode Current Choke Test Rig I’ve had several people ask me this question, and it’s a good one.
