The display is rather small, assuming 2.3" and I can barely read the SWR values with my reading glasses. So based upon what I reading here what I bought is not the latest (-F or -H4) is my assumption accurate, excluding the V2 and/orSAA2 I see posted above ? Should I return and get the -F or -H4? On the back is a sticker NanoVNA-H, H/W version 3.4, 50k-1.5GHz. I just ordered and received today a 【Upgraded】AURSINC Vector Network Analyzer 10KHz -1.5GHz HF VHF UHF Antenna Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart(Latest Version REV3.4) from Amazon.

If you want cutting edge (hobbiest) technology, you should go for the V2 that goes up to 3GHz - BUT - the current version only has a 2.8inch display. Personally, as a starting point, I would get the H4 version as it is useful up to about 1.3GHz. There is a recent thread on the pros and cons of each in the forum.
The F is different in terms of its uP and operating system and its twice the price but has a full metal enclosure. The H4 version has the same RF and operating system design but with a 4inch display and a uP with larger flash memory for about $15 more. The unit you purchased is the latest version of the 2.8 inch Nanovna.
