AURSINC NanoVNA Vector Network Analyzer, 10KHz-1.5GHz HF VHF UHF Antenna Analyzer Ham Radio with 2.8'' Touchscreen HW V3.5

I am very happy with this after having used it extensively for the last couple of weeks. A perk of my profession is that I get to use really expensive and capable test equipment at work but I wanted some of that capability for my hobby projects. That said I went into this purchase not expecting professional quality gear. My expectation was for hobby equipment and I feel like this product fulfills that expectation quite well.There is plenty out on the web regarding what this does and does not do, so I won't rehash that here. I will say that there are many firmware available for this and some do different things, or do some of the same things differently. In any case, you will likely want to update the firmware on this or try one of the others. It is quite easy to do.This particular unit came in a plastic case with a couple of cables, an SMA F to F barrel, and the terminations for calibration. A USB cable is also included along with a nice stylus, something that is absolutely a must for the operation of the touchscreen. Everything you need to get started is here except documentation. That's reasonable because any documentation will be specific to firmware and firmware changes often. So you'll get that yourself electronically and you'll likely want to watch some videos as well to get up to speed on the operation of it.The included plastic case might be ok for some, but I recommend you put this into some more robust storage when not in use. At this price what you are getting is somewhat delicate and exposed. That's fine for a reasonably clean bench. I've even used it with care in the field. Just know that this isn't something you're going to casually throw in the tool bag, you're going to want to protect this.So far I have enjoyed using this for a number of tasks including: sweep antennas, tune filters, tune antenna traps, measure inductors, measure capacitors, and so much experimentation with tuned circuits. Not only has it increased my productivity on my hobby bench, it's really helped me to learn some concepts and reinforce others. What a pleasure to be able to do that without worry because if I harm this thing in the process that's a whole lot different than playing around with my professional test equipment at work that costs tens of thousands of dollars.In conclusion, this is a nice inexpensive bit of kit that produces reasonable results for the hobbyist. I am quite pleased with it.

I mean you know what it's going to do. It's going to give your next WR reading for $50. And that's just plain magic

Works great indoors but very hard to see in sun light

NICE ITEM,THIS NANOVNA IS THE ORIGINAL DESIGNED ONE.NOT THE KNOCKOFF.IT IS A GOTTA HAVE FOR ALL YOU OUT THERE THAT LIKE TO TUNE YOUR ANTENNAS TO AN EXACT FREQ WITH GREAT VSWR EASILY.IT DOES MANY MORE THINGS THAN THAT BUT MOST OF YOU OUT THERE WILL PROBABLY WANT O JUST GET THAT ANTENNA TO MATCH AND CHECK TO SEE IF IT PERFORMS AS ADVERTISED ON THOSE FREQ THEY HAVE LISTED.IT HAS A SLIGHT LEARNING CURVE SO DONT GET FRUSTRATED AND SEND BACK BECAUSE YOU WILL FIND THAT YOU WILL BE VERY HAPPY WITH IT ONCE YOU KNOW THE BASICS.ITS A VERY VALUABLE TOOL FOR ANYONE LOOKING TO MAKE THEIR OWN ANTENNAS AND TUNE THEM TO THE FREQ THEY WANT.GO ONLINE AND GOOGLE HOW TO TEST SWR ON NANOVNA AND SAVE IT SO THAT EVERYTIME YOU TURN UNIT ON IT WILL BE READY TO GO FOR ANY TEST AS LONG AS YOU SAVE IT WITHIN THE FREQ RANGE YOU USE AND YOU WILL NOT HAVE TO CALIBRATE IT EACH TIME YOU TURN ON.IF YOU SAVE YOUR SETTINGS IN BANK 0 IT WILL ALWAYS SHOW THOSE SETTINGS EACH TIME YOU TURN UNIT ON SO THAT IS QUICK AND FAST.IT REALLY IS VERY EASY TO LEARN TO USE IF YOU JUST WATCH A FEW VIDEOS ON YOU-TUBE...SO GO CHECK IT OUT YOU REALLY WONT BE DISAPPOINTED AND YOU WILL SOON FIND OUT THAT YOU WONDER HOW YOU GOT ALONG WITHOUT IT.

I ran a controlled test of three NanoVNA-H instruments compared to a $600 RigExpert AA-600. Precision <1.0%, Accuracy <5.0%. Determining minimum SWR for antenna resonance frequency is spot-on. SWR values for 142.355 MHz were: RigExpert 1.25, NanoVNA-I 1.19, NanoVNA-II 1.19, and NanoVNA-III 1.20. I turned all units off, then back on, recalled calibration from memory, repeated test and got the following: RigExpert 1.26, NanoVNA-I 1.19, NanoVNA-II 1.19, and NanoVNA-III 1.20. So, I am very pleased with such a tight precision among three different NanoVNA-H instruments. However, the unit is very small and fonts on the display may be impossible for old eyes to see. It is fine for me, and I use a stylus on the touch screen to make entries. Finally, all VNAs are not the same. You may find a cheaper price for what looks exactly like the NanoVNA, but later find it does not come with all three calibration caps, or cables. The three that I purchased did not come with an instruction manual. This needs to be shored up to make it easy to download manual and computer software. I am slowly finding everything I need on the internet, and have joined a users group where I live. So, choose wisely and have fun.Tim E. SpurgeonW0TES

There are hundreds of versions of this out there, this one is a good build and accurate if calibrated correctly. I use this mainly to check the swr on my antennas. I have also used it to trace the length of coax to a fault. It excelled at both of these functions. I use this all the time in my Ham shack when building new antennas. You must calibrate it when changing the stimulus settings. Also, it only keeps 100 calibration points so calibrate it only to the range you need for the best accuracy and always save to bank 0 as this is the bank it recalls when it is started up.The build on it is sturdy enough for bench use although I would not throw it in my field bag without keeping it in its plastic case. The case on this is open on the sides so using it in rain is a no go. The touch screen is good but better if you are using a stylus. For the price it’s the best antenna analyzer I have ever used. There is a bit of a learning curve with setting it up if you are used to a regular ham antenna analyzer but nothing that five minutes on YouTube won't cure.KI7FHU 73 all
