Really valuable instrument, with lot of options for the price. A single BIG defect, luckily quickly solved googling around: the touch screen responds randomly, sometimes by its own, sometimes not reacting to taps. I discovered that the plastic box is slightly thick and "pushed" the touch screen on the side. Putting four plastic washers between the two halves of the enclosure at the screws and screwing back all, solved the problem.

Shipping is super fast as usual. Packaging is OK, but plastic could not protect the paper box (which is nice, but not very practical). As I have an older NanoVNA-F I can compare H4 with it. H4: Electrically it's better without hesitation. It has no trouble to keep everything below -60dB till 900MHz, and -50dB till almost 1.5GHz. This is really impressive. It's lighter due to plastic case (I regard this as a positive thing). LCD size is a bit smaller than F, but as there is no scale it looks almost the same. LCD visibility (especially from SMA side) is slightly worse than F. Touch reliability is slightly worse than F. Pushable rotating knob is still nothing to write home about but it seems to work. So far I could not locate a new SW version (I mean binary as I'm not keen compiling it myself). In addition the menu cheat sheet contains a DFU menu that is not found on the actual menu of the SW... So it's unclear to me how firmware update supposed to be done if it's necessary. In overall it's light and electrically so far the best package (it's a very good value). I look forward seeing the V2 variant with a similar size display.

This time the Nano VNA is working. The box was a bit smashed from on edge but no damage inside. Very handy very useful item. Worth for the price no doubt.

Having a few of the original 2.8" NanoVNAs which I have found excellent units, especially with the latest firmware, I decided I needed the H4 version as the display is much clearer - especially for my old eyes! The increased Frequency range is also an advantage, So if you cant decide on the original or this H4 version - spend the very small amount extra & buy this H4 version. I am also impressed that all my purchases have been delivered within 5 to 6 days to the UK.

Received in good condition in the black cardboard box that is generally seen with these, 2 x pigtails, open, closed and 50 ohm load etc. Casing is plastic but pretty good quality I think and is light weight and sturdy. 4" screen and larger is a must. I am glad I did not go for the 2.8" version. Battery life is pretty decent. As a radio ham I purchased it to replace my SARK for SWR and to play with filters and for building and testing VHF/UHF antenna. So far I am extremely impressed with this unit's performance after calibration. It is no commercial VNA but for my use it is perfect and any HAM's use it should be perfect. Filters built using software and then tested on the bench with this unit have produced the same results as the software emulation. Checking crystals for matching works well too. Tested various antenna I have from a slimjims to multi band yagi and some dipoles that are in use and were setup with a commercial meter and result are the same, very happy with this VNA. Downloaded software for my android phone and used the cable length test, very accurate. Think it is excellent value for money and the better of the units available from Banggood especially if you are going to use it outside for antenna tuning, then a unit in a plastic or metal case is a must. The only unit I would maybe consider as the next purchase is the 50KHz-3GHz 4 Inch Display Antenna Analyzer SAA-2N from Banggood.
