If you are only going to make measurements up to 1 GHz then you'll be happy with either unit.

They each operate from 10kHz - 1.5GHz with their current firmware, although the performance of the NanoVNA-F starts to get iffy above 1.3 GHz. I own both models and I am happy with either. Both the NanoVNA-H4 and NanoVNA-F already incorporate identical out-of-the-box TDR measurement capability. 'I would like to use TDR one day, any clue if a version running it will be released soon?' This user group beats the NanoVNA-F user group hands down when it comes to support, which adds immeasurable value to the NanoVNA-H4. It proves to me that while the NanoVNA-F may be slower at introducing new firmware updates than the NanoVNA-F that the developer is fully capable of keeping up with any worthwhile new features.

With firmware release 0.1.1, the NanoVNA-F incorporates pretty much all of edy555's 6.0 firmware improvements and adds a few of its own. Up until about a month ago I would definitely have said the NanoVNA-H4 was the better developer supported model. 'I would like the 4.3 or 4.0 inch display, but it's look like the F and H4 version are not the same processor, so wich one is the more supported model?'
