    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

    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.

    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

    Package arrived promptly by the royal mail postman exactly when promised. All in good condition with all the bits present. Vna is within a nice finished plastic case to cover all the PCB. Display is nice and bright and all controls (2) work just fine. Comes complete with two short sma coaxial leads , one female connector barrel and the calibration plugs. Also complete with one short mini usb to usb lead and one large USB to small usb lead short of one metre long.

    I just recieved my new nanovna-H4 today and it's beautiful! I've already added a TF card slot and the 32khz xtal for the real time clock (DiSlord's firmware from June 20th) The unit is from Hugen's manufactuer as well (at least the unit from the batch I bought from). Shipping to Canada was great - unfortunately, Canada Post sat on it for almost a month. Thanks Banggood!!

    This VNA is a self contained portable instrument with a 4 inch screen which is easy to view. The VNA came calibrated and initial testing showed good accuracy. Tested S21 accuracy better than 0.1dB to -50dB, S21 noise floor at -78dB, and S11 accuracy better than ±1dB at -30dB (VSWR 1.06:1). The included 50Ω calibration load has a similar response to my NARDA load up to 900MHz indicating very good quality. Item supplied as a complete kit, this is a very good product. Thank You.

    My second order of this VNA. It initially had and issue with a non-responsive LCD screen, but after cleaning the LCD contacts soldered to the PC board all was well.

    This is a fantastic device for antenna analysis. Instructions leave a lot to be desired and using the device can be confusing, but once used, it isn't too difficult. Because of COVID and ocean shipping, this device took three months to arrive from date of order.
