However, recently there has been anti-competitive behavior from one clone manufacturer that I won't name, and it involves manipulating rankings on platforms like taobao using fake orders and reviews, as well as dumping devices at close to cost to overseas reputable distributors. I like to see variants like the 3.2 inch 'black gold' clone, and even recommend them when people ask me where to get a S-A-A-2 with metal enclosure. So far the vast majority of clone manufacturers are playing completely fair and we are fine with them selling S-A-A-2 devices. We released the design as open source and do not take any royalties. In fact, we encourage making variants of the S-A-A-2 design, or even verbatim clones, as long as basic business ethics are observed. You will also learn a lot! It's a wonderful, amazing device.On behalf of the S-A-A-2 design team I'm writing this to clear up confusion around our stance towards clones.įirstly, we do not have a problem with clones. For the binding posts adapter, you'll also want a 50 ohm resistor for doing calibration.Īnd whichever you choose will bring you a lot of capability and probably a lot of fun. The binding posts adapter was nice for testing toroid impedance matching transformers I was making, for use with high-impedance antennas. I've added male & female adapters for BNC, UHF, and F connectors, plus a BNC-binding posts/banana jacks connector that's good for testing wire-lead components like toroid coils. A small case with dividers inside is also very handy for storing and organizing the adapters. Whichever you choose, be sure to also order connector adapters that you will need. All models seem to have very good PC software support. The -H is much smaller and lighter, easily fits in a shirt pocket, but is harder to read and VERY hard to read in bright, outdoor light. I really like my -F, and also have a -H that was my introduction to NanoVNAs.

I believe it's also a bit more expensive, and uses a different firmware version (I think).

The SAA2 would be preferable if you need measurements above 1.5 GHz and/or need to use type N co-ax connectors. There are several programs for Windows (including 10), and one for Android. Also I am not sure if either of the software programs will run on Windows 10?
