[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 love this thing, it allows me to tune across a much broader band than an swr meter does, a very convenient feature for ham users where we have access to multiple bands not just one like cb users. It also allows tuning an antenna without the radio present, this is great to find resonance on the antenna without having to constantly key up across the band or multiple bands. Downside is it is an sma connector, which means for anything not sma you need adapters. It also can be difficult to learn at first. For the price point even figuring initial difficulty it is worth it to be able to tune with easy over oldschool swr meters for ham radio.

So far, so good. MAKE SURE YOU CALIBRATE IT! The little cap pieces that come with it are for calibration. Search for a video on how to calibrate and save start/stop ranges. This is definitely a step above beginner for learning how to use, but if you spend some time watching videos on how to use it, you will get it. This is great if you like building your own antennas, or you just want to see what’s going on with purchased antennas and what frequencies will give you the best results. Although, checking SWR is just the beginning of what this device can do. Don’t waste your time and money on other SWR/Power meters when this is available at this price point. It’s worth the effort of learning how to use the NanoVNA.

This little thing works great and seems very accurate it gives you much more information than an swr meter alone to help identify weaknesses in your setup. It’s well worth the investment especially compared to repairing an expensive radio if the antenna is not matched correctly. It helped me identify a bad section of coax in my setup which was causing higher than normal swr readings and quite a bit of noise on receive and transmit.

This little really works. I got it to check SWR on my antennas and it's made a big difference. Down side is the complexity and difficult to read screen. I keep a small magnifier with it to help read the screen. There are no instructions with it so YouTube is your friend. There are many good videos with step by step demos. The device has many features. So many that I was overwhelmed. But I was able to measure my SWR, which was my main purpose. Overall, for the $$$ it's a real value.

This is the best Amazon purchase I’ve made in years. Spend a few minutes watching videos to learn the basics. I’m only using it for serious and it works Amazing. I’ve only had it a short time but seems built great. I love the way it looks super professional. It was a breeze to get connected.

quite incredible, took about 20 minutes to get a basic knowledge and learn how to use it... great product, i recommend this 100% i might buy a second one for as little as they cost

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.

NanoVNA-H is a must have. It probably has more features than what most need but it's an invaluable tool

Reçu le colis a 19:00. Livré comme indiqué c.a.d aujourd'hui. Je n'ai pas encore testé le nanovna, il a été livré en Bonne condition, il ne testé plus qu'a effectué Les tests. En date du 7 février(2026) l'appareil semble bien fonctionne.

Dentro da expectativa.

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
