R&L form too....

John K0JHL

I second R&L for USA purchasers. They have a very good reputation. I purchased my Ultra from them. My original first run Tiny was purchased direct from Erik's supplier in the days before the vendor list. These days I prefer that all of my money go direct to the vendor rather than giving Amazon a cut. Some of the users in this group can advise on where to get the good VNAs. I got lucky and accidentally bought my early -H from the right eBay vendor before I learned about bad clones.

That's not my experience - if you order something that is listed from the Aursinc store, you'll get one from Aursinc. Same with other stores on Amazon. But maybe this doesn't happen if an item isn't listed by a store.
But I also got my NanoVNA from R&L - they are a great business to support.

The problem I have with amazon for this is that you have absolutely no guarantee that you'll get a unit from any particular supplier -- they'll ship what they find convenient to ship, so you may get a good one, or you may end up with a clone. For some stuff it doesn't matter but I'd prefer to order from one of the recommended vendors;.

For whatever it's worth, I got mine from R&L.

Thanks, but that does not really change what I wrote. Best to buy direct from the vendor IMO. The OP did not know about authorized resellers. I already own both Tinys purchased vendor direct. The same goes for the VNAs. Personally I avoid Amazon as a general rule.

Jim,
If you check the TinySA group WiKi, you will find TWO approved vendors on Amazon for the TinySA and Ultra or TinySA4.
They are SeeSii and AURSINC.

As far as the NanoVNA H and H4, R&L Electronics, in the US, is highly recommended as well as AURSINC on AMAZON.
I have purchased from all three vendors, and received original versions of TinySAs and NanoVNAs.

Thank you very much Karl

Do not buy a TinySA on Amazon. You will likely get an inferior clone. Approved seller scan be found in the TinySA Wiki.

Antennas on high towers are difficult to test. How about an relay box with OSL standards inside at the antenna terminals.

Hi Matthew

Thank you very much, it's done with youtube , Clear Now ,

While similar in some respects, the nanoVNA and tinySA are completely different designs and completely different instruments.
The nanoVNA does not display the time on the screen - it is used for automatic naming of capture files, and for placing a timestamp inside saved .s1p, .s2p and calibration files.

Hi Matthew

pse can you pointed me what Navo VNA you recommend to get, NANO-VNA H4 or TinySA ??
wanted with open source , 4'' screen with efficient touchscreen function if possible.
Thanks

Curious... I set the date & time on my NanoVNA H4, but nothing appears on the screen. When I did this long ago on my TinySA ultra the date & time display in the lower right corner. Am I missing a step to get date/time displayed on the NanoVNA?

Amazon.com - I recommend this unit based on previous research.
