Upgraded NanoVNA-F V2 Vector Network Analyzer 50KHz-3000MHz HF VHF UHF VNA Antenna Analyzer 4.3 Inch With 5000MA-H,Measuring S-Parameter Voltage SWR, Phase, Delay, Smith Chart Review

Very handy analyzer for the Amateur Radio Operator or radio enthusiast. I compared readings with my more expensive antenna analyzer and they match up very closely. The Smith Chart is very handy to have as well as being able to see reflected db. You get a lot of information from this little unit. The only thing that I have found that I do not like is that the control wheel is a little touchy/unresponsive at times. I think that push buttons would probably work better in it's place but not a deal…

I have the smaller unit but with the large screen this F model is a lot easier to use. I appreciate the metal case for durability.

Impressed with the features, functions and operation of this VNA. I have used it to align my UHF and VHF Satellite antenna array as I was able to take it out to the antennas and connect at the base of the antennas. What you get for the price is very impressive. Battery life was no problem for me and external use.It comes in a nice Plastic case with custom fit foam for all the parts. I like the larger screen on this model as it is easier to see the data but also use the touch screen features. No

The fact that VNAs can be had at this level of quality, for this level of budget, will alter the amateur radio culture forever. Now it's within reach for even new hams on constrained budgets. If one can't afford this model F, there are even cheaper options. So with salvaged wire and an investment in a device that costs less than a decent HT, one can make fantastic antennas and get them resonant for transmitting around the world.This is perfect for tuning loading coils on vertical antennas, or…

The Nano-VNA works surprisingly well considering its price!The calibration tools in the kit are not super precise and one of the calibration tool cannot fit with the VNA port. But if I calibrated the NanoVNA with some calibration kit from an expensive VNA, the Nano VNA's results are very close to the expensive VNA's results, so I would say the Nano VNA is pretty good!

It’s well built, and a valuable addition to my shack. Great for trouble shooting antennas and improving performance. As well as a many additional functions.

This unit is amazing.I own scopes and even a spectrum analyzer, but never had a network analyzer at home. I've used many at work, including the HP/Agilent 8753 and 8510 series. They were all too big and pricey. This little NanoVNA-F does 80% of what I would use those for (at least in the frequency range it works in).About the only thing missing is port-attenuators - but this is 140 bucks and the 8753s are about 3,000 bucks on the used market. And you can't move them around like you can this…

I have two expensive Antenna Analyzers in the shack, costing > $300. They work well, but cannot do as well as the Nano-VNA. It is a treasure for anyone wanting to work with antennas. There is free downloadable software to run on a PC, which makes measurements from the ham-shack a delight.It is VERY accurate, easy to calibrate and quite easy to use. The menu is quite nested and takes some getting used to. It is easier to use from a PC.I have used it to carefully measure the following with…
