[Upgraded] AURSINC NanoVNA-H Vector Network Analyzer 9KHz -1.5GHz Latest HW V3.7 HF VHF UHF Antenna Analyzer, Measuring S Parameters, SWR, Phase, Delay, Smith Chart

I didn’t want to spend hundreds of dollars for an antenna analyzer that I might use a few times in my entire life. This was inexpensive and it works fine. It seems like it would be very complicated and difficult to use, but there are lots of videos on YouTube that show how to use it, and if you just follow the steps, it works fine and is not difficult at all.

Should have bought this a long time ago. I recently purchased a cheaper version of this without the case. For a few bucks more. I suggest you buy this one with the case and the ability to take a microSD card. Item came well packaged and it works straight out of the box. There are a numerous tutorials on YouTube on how to calibrate the meter. I suggest you watch them as it is pretty easy to do and take a a few minutes to do. This is just another tool to add to the ham box. It also a very useful tool to test out antenna to show you what band is the antenna is cut for and the SWR you're getting back to the radio. Don't solely rely on this. But it's a great tool to give you a baseline where the antenna "sweet spot" its at. I tested several HT antenna you can clearly see where the band or bands the antenna is at. Great and awesome tool for ham operators. Very well made and happy with the purchase.

Interesting box.. it does a lot. I really like it and seems like it is a good unit. I have not had time to do as much with it as I like, but it has done what I wanted to do. I use this with my Amateur Radios. the size of this, you can even carry it to the top of a tower and use it, or any remote location.

The less ideal: Virtually no instructions unless you do some searching online, in which case they're easy to find. Included USBC cables are so tight I decided not to use them. Cables I already had were perfect fits (how do you mess up a USBC connector?) And though it claims to have an android app, the app is outdated and doesn't work with newer android versions. Ok, now we've gotten that out of the way. Now for the good parts: Easy to interface with computer, great features, not expensive, does things that you used to have to pay a lot more for a few years ago, hundreds more. I was able to easily see my antenna's behavior over the frequency ranges I need to use it for. It made tuning the antenna simple. It also made it easy to observe the cutoff points of my diplexer. It's just so useful and amazing to use. I'm really happy with the purchase.

This is the first device I have owned like this. As a ham hobbyist, I was used to a standard analog SWR meter. I could tune an antenna to get decent results. I did not know what I did not know. Wow! Having the extra capabilities and ability to analyze antenna efficiency across a frequency band is incredibly helpful. This specific device is very serviceable. After reviewing a couple YouTube videos on setup and calibration of the device, I was up and running. This unit is the older version format with SMA connectors (newer / more expensive version uses PL239 connections). The package included the device, 2 SMA male/male cables, calibration connectors (open, short, load), a stylus and a wrist strap with guitar pick-like stylus. There is also a usb-c to usb-c jumper cable to connect the device to a smart phone. The device powers up quickly. Once you get frequency ranges set and calibrated you can store them in 1 of 5 memory slots. A few more would be nice but 5 is very serviceable for my needs. The touchscreen is the resistive type (think old PalmPilot). That is why the guitar pick stylus is a nice touch. It can be a bit finiky and sometimes you have to tap twice or you may hit a soft button you don't intend to. Patience and remembering the feel of the older PDA days is helpful. So far, I haven't gone into settings that messed things up or couldn't be backed out of easily. I can't provide feedback on the precision of the device as I do not have anything to compare it to. However, results do speak for themselves. I have been able to diagnose some antenna and feedline issues on several setups and get them resolved. Much improved function of my antenna systems. Battery doesn't last as long as I had expected. About an hour of continuous use (best guess - I haven't done a full battery function test). Not an issue though as the device works while plugged in for charging. There are several options for the type of graphic display of the signal results. I mostly use the SWR but am learning the Smith Chart and like it very much. More fidelity of information. I have had no issues with the product so I haven't needed to contact customer support. Product is functional and more finished than earlier versions of the NanoVNAs I have seen online. Overall, I highly recommend this product. The range of functions are far more than my ability to use. For the price point, you can't go wrong.

Muy buena compra y buen producto per se me hace complicado

La batería por más que la cargues no dura la carga, Un pigtel se desoldo super rápido, no retiene carga, de ahí en fuera es bueno el funcionamiento
