I am also interested in the difference.

Steve,
I believe no one has replied to the original post because it is hard to find members with both devices. NanoVNA-F owners are pretty satisfied with their devices and the same will go for NanoVNA-H4 owners.
Both devices are based on edy555's original design but are implemented differently:
The NanoVNA-F has a 4.3" Display with better resolution than the NanoVNA-H4. It is packaged in a metal case and has a massive 5000 maH battery. Updates to the firmware are via a built-in virtual disk that shows up as a drive when connected to a pc. The frequency range is 50 kHz - 1 GHz.
The NanoVNA-H4 has a 4" Display. It is packaged in an ABS case and has a 1950mAh battery. Updates to the firmware are made using a software program via a USB connected pc. The frequency range is 10 kHz to 1.5 GHz.
The NanoVNA-F is about twice the cost of the NanoVNA-H4. My ham club has both devices and either is a great choice. I own a 2.8" NanoVNA-H and wanted a unit with a larger display. My personal decision was to purchase the NanoVNA-H4.
When hardware specifications are fairly close, support becomes the deciding factor for me. This support group and other forums around the internet are hands down better than any you will find for the NanoVNA-F. hugen has available numerous other developers (i.e. edy555, QRP, etc.) that contribute outstanding firmware functionality at a rapid clip. Firmware releases for the NanoVNA-F are historically slow and sometimes are rather mundane, such as allow you to add your call sign to the boot-up screen instead of something more substantial like the TDR functionality of the NanoVNA-H4.
Again, both units are based on the same design so there is a lot of overlap in their performance specifications. This user support group, the independent firmware developers, and the increased frequency range specifications were my reasons for deciding on the NanoVNA-H4.
Hope that helps.
