I purchased the H4 from Alibaba. I'm very satisfied. It was $70 USD delivered in less than a month.
The vendor was recomended by a microwave group I'm a member of.

I am looking for a nanoVNA that will cover 23cms band and has a larger
screen that my old eyes can see :-(
At the moment, there are several Ebay sellers offering what appears to
be the 4" screen 1.5GHz version of the nanoVNA at a very attractive
price? (attached screen grab)
The pictured device claims to be a 4.2 Version (I assume they mean
firmware?) so seems pretty current?
However they call it an Antenna Network Analyser rather than VNA.
I am sure I read on this group that when upgrading the firmware there
is VNA, and a separate Antenna Analyser firmware.
Also there is a spelling mistake in the on-screen menu :- MARKER is
spelled MARKEY leading me to suspect it is a clone?
I would welcome all your experienced advice and advice please :-
1) Has anyone purchased one of these devices recently off Ebay ?
2) Is it running the full VNA firmware ie. Logmag, Phase, Delay,
Smith, SWR, etc?
3) Does it have the full input screening?
4) is it a Hugen device or a clone?
5) how well does it work at 1296MHz
Having bought a cheap nanoVNA only to discover is was rated as a BAD
clone on this forum (and spent today adding screening cans to 'tame'
the input noise), I thought I had better get some advice from you
before making the same mistake again.
Thanks in anticipation.....
