NanoVNA / SAA-2N ver/v2-2

 

My first VNA SAA-2N in 2020, love the large SO-259 connectors instead of SMA connectors. I notice that my touch screen is not working right. Hit display nothing happens, trace doesn't do anything either. Can this be corrected.
I purchased a new NanoVNA F V2 that was 3x what I paid for the SAA-2N. I don't like the menu layout or the SMA connectors. The 2 RF cables are so stiff they hardly bend, afraid using them I will break the SMA connector on the Nano.
What is the difference between the F model and the H model. Cause I may return this F with these 2 stiff RF cables
 

I believe it is:

F has metal case and much better display when used outdoors. People like it for field testing because of ruggedness and display.

I think the H has more features and more active FW development.

I have F v1 and a H4.

Try removing and re-seating the display cable. Mine showed a white screen (gave me a mini heart attack) but re-seating the cable restored normal operation.

I have the F V2 and it is everything a person could ask for except the inclusion of and SD Card and lacking of Dynamic Range for filter measurement.
For working with antennas is simple and allows a person to take the VNA to the antenna for precise measurements without the feed line influence.
