I'm looking to purchase my first NanoVNA and I'm overwhelmed by which one to get. By chance have you done reviews of the other VNAs your club has purchased?? ============================================================== Dallas, You might want to check the review I did of the NanoVNA-H4 at /g/nanovna-users/message/10012 . As a first time buyer I would limit my choices to the NanoVNA-H ver3.4, NanoVNA-H4, NanoVNA-F or S-A-A-2. The NanoVNA-H ver3.4 has the latest board modifications by hugen and limited measurement capability approaching 2 GHz. It is also the most supported version by firmware developers. Its drawbacks are a 2.8" display, slower processor, and limited flash memory. Almost all current software supports it. The NanoVNA-H4 also has hugen's latest board modifications and limited measurement capability approaching 2 GHz. The 4" display is an improvement over the NanoVNA-H and it has more flash memory space and a faster processor. It should be more future proof than the NanoVNA-H. It is not as well supported by firmware developers as the NanoVNA-H. Currently hugen is the only developer with official firmware releases for the NanoVNA-H4. Almost all current software supports it. It is a fairly new product and problems with the case fitting has been reported by some users. The NanoVNA-F has the best display of the NanoVNA variants. It is a 4.3" display with about twice the resolution of the NanoVNA-H4. It has more flash memory space and a faster processor than the NanoVNA-H which should make it more future proof. It has a metal housing versus the ABS housing of the NanoVNA-H v3.4 and NanoVNA-H4. It is not as well supported by firmware developers as the NanoVNA-H. Currently BH5HNU is the only developer with official firmware releases for the NanoVNA-F. Almost all current software supports it. The most current versions are 2.3 (Thumb wheel switch) and 3.1 (Push button switches). Older 2.2 versions are available at a discounted price, but have more limited capability than the newer versions. The S-A-A-2 (NanoVNA-V2) is the only game in town if you want to make measurements up to 3 GHz (fairly good to 3.5 GHz). Its 2.8" display, lack of accessories, no protective housing, no battery and limited software/firmware support are its primary negatives. It currently has limited availability as its first production run was sold out within a month. Subsequent production runs may address some of the negatives I mentioned. - Hope that helps. - Herb |
