Two problems with harmonics is the drive signal is very low and your circuit is still seeing the fundamental, with it's level. With the high price of the V2Plus4, lack of firmware support and lower frequency range, I recommend the LiteVNA. The H4 may be good enough for you personally but I tell people that if you want to experiment beyond 300MHz, get something else. You can see both the H4 and original NanoVNA. Some of this data was provided by various owners. ' I have posted data showing how some of the low cost VNAs compare. Once you move beyond that 300MHz, shit hits the fan. I was pretty impressed when I first saw this and it was a major letdown to see the higher end V2Plus4 not performing at least as well. My original NanoVNA is about 10dB higher. Noise floor for my H4 up 300MHz is around 85dB. UHF covers 3GHz which unless they have further increased the range of the original NanoVNA and H4, you are missing half the band as the highest I have seen them allow was 1.5G. I think that will depend on your definition of "suitable".
