The H4 has a plastic case, unless someone repackaged it. Metal case units have a different name, different support (don't remember what it is).
Don't shy away from the plastic - it works very well, and does not seem to suffer from a lack of shielding.


 

Hi Stand
Thanks for info, did you mean that plastic cases used on H4 has inside an aluminium painted layer for good sheilding ?? So no mater if case is metalic or plastic ..

The SAA-2N, which I have and recommend, is in a steel case with 4 inch display and with type N connectors, and the test cables and calibration standards are also type N. The cables and standards are robust and appear well-made. It comes in a nice carry case.
I have two of the other nanoVNAs and the SAA-2N is the one I reach for the most. https://www2.randl.com/index.php?main_page=product_info&products_id=75242

They have internal metal shields on the PCB assemblies.
