LiteVNA-64 VNA Analyzer 50KHz-6.3GHz Portable Vector Network Analyzer Antenna Analyzer 4" Display

I'm using this for WiFi and Drone VTX antenna testing and tuning. This VNA needs to be capable of running at 5.8GHz for it to be useful for that application. So far, my testing has proven this little unit to be valid there, which is awesome. Antennas that I knew were working showed up as expected in the plot. Antennas that I had that were suspect showed bad characteristics in the plot. Pictures are of some quality cloverleaf antennas I made, plotted with this device and the freeware app.One thing I will say bad, and this is really only about the art in general, is that everything is incredibly sensitive. Merely re-torquing the SMA connector changes the tuning up/down by an entire channel. An SMA torque wrench would be much better than just my fingers.

I watched a ton of reviews for these. There is a more robust version out there that apparently has a dedicated high frequency oscillator. But this one works fine for hobby grade tinkering.

I like the size, the 4 inch display is a big improvement from the tiny display on cheaper units. The internal battery lasts fie hours of use and recharges very quickly. When compared to other antenna analyzers, it us better in almost every way ad well as being able to be used fir many more functions than just antenna work. Besides tuning antennas to the proper frequency, I have used mine to tune a bandpass filter, calculate the velo itu factor of coax and used it as a weak signal source for checking UHF and microwave radio receivers. The biggest complaint is trying to use the touchscreen or shuttle wheel to access menu options, both leave something to be desired.

Love the device it works well when plugged into my bush port. However take it to the field and the internal battery lasts about 30-49 minutes then it’s off and needs to charge again.If anyone knows of a solution to this please let me know.Will be happy to take this to 5 stars if I can fix the battery issue

This VNA is fairly user friendly, at least in my opinion from my experience with VNAs. The unit does appear to operate up to 6.3GHz as advertised (well at least with a thru device, S21 is flat across its functional band). Thus far, I used it to characterize several antenna, very handy for that need.

Received VNA allegedly in new condition, but it didn’t work as it should due to touchscreen not functioning correctly. Multiple attempts to calibrate touchscreen function didn’t solve the problem. I was unable to check if any VNA function works due to not working touchscreen. It looks like no QA at all.

This product works great. Dynamic range at 6 GHz is better than 60 dB. That is good enough for 80% of most users common tasks. Measures fast and accurately.
