SEESII Nanovna-H Vector Network Analyzer,Upgraded HW3.6 10KHz-1.5GHz MF HF VHF UHF Antenna Analyzer, Measuring S Parameters, Voltage Standing Wave Ratio,Phase,Delay,Smith Chart,Support Data Storage

Works really well. Sci fi level status. I love it! It does take some getting use to and is not as easier as the old school ones but just has so many more capailities and is very good for the entry level hams. Plus its not as nearly expensive as the other two big names. Yes... i do have others. This one is compact and portable with spot on accuracy. Only downside is the open, short, and closed calibration situation..but just make sure to save that parameter profile for the band you will be measuring and you wont need to do it again. Thank you so much i will definitely buy another one.

I'm finding this very useful, and still amazed by all it can do. It's a bit of a learning curve....in fact I'm still learning all it's functions, but executes tasks very well. I found it handy for working with home brew antennas for ham radio. More functionality, and much cheaper, than a mainstream antenna analyzer!

As described and work great for tuning antennas swr

Works great but has a learning curve. You will probably need some adapters if you need too test antennas. Luckily there are many helpful videos on YouTube that will get you started.

Dang it is small for old eyes. I have only used it in my 'shack' so cannot comment about outside visibility. I have a Diamond 5 band trap antenna and wanted to tweak the radials a tad. There is a menu print out in the box but nothing else. I had already downloaded a couple of how to documents. Both documents commented that there are several versions of the Nano so your screen may look slightly different, I played with it a couple of hours before connecting my antenna (remember to get the adapters if using the vhf 259 type connectors). It was intimidating at first but after running through a SWR set up a couple of times, it started to make sense. I had three bands to set up so used the same trace and changed the frequency range. You have to recalibrate when changing frequency so really not a big deal. You can save four traces. The recalibration is simple. Takes maybe two minutes but if you don't do it, a doubt your readings will be accurate. To me, it is well worth the cost.

Though the learning curve is a bit steep, this is a great tool for testing and setting up ham radio antennas. A good value as it is considerably less expensive than most of the antenna analyzers on the market.

Great tool for tuning and so much more. There's a learning curve but don't be intimidated. Once you figure it out, it delivers as much and more info than a Rig Experty AA-35 Zoom or an MFJ 259(x). I have them as well but the Namo VNA is just more info. Smith chart is a bonus.

Zero complaints with this Nano VNA and it it functions very well. Only things worth knowing before you buy is these MUST be calibrated to a more narrow bandwidth instead of it's full range every time you switch to a different band portion you want to test, that goes for pretty much any Nano VNA available for them to be very accurate. These have a wide useable range from 0.01 MHz to 1500 MHz and like any other Nano VNA they're limited by how many data points they can spit out over a given range, think of that wide range like a huge "cake" that can only be divided into say 10 equal portions (data points). But say you want to test a 70cm/440 MHz antenna? Select a smaller area of the "cake" say from 420-450 MHz where the antenna is actually useable or an even narrower range first if you want better test results and the Nano VNA will still divide that smaller portion into 10 equal parts giving you more accurate data results. I'd also recommend getting a fine tip touch screen stylus to make navigating the menus easier, that can be a bit frustrating if you have fat fingers.
