Looking at the number of different versions available on Amazon, I'm confused. Although not an abnormal state for me, I try to keep it to a minimum.

Can the group make some recommendations for a nanoNVA version fo antenna tuning and other uses not known to a new user on a nanoNVA?

thanks for any recommendtions,
Bob

I bought a NanoVNA-H v3.6 recently and I am happy with it. I use it mainly
for antenna tuning.
Here is my little 'NanoVNA for Antenna Tuning: A Beginner's Guide':


Other uses which I have tried are:
Measuring the characteristic impedance of a coax.
Measuring length of a coax (actually distance to first fault).
Testing a unun for End Fed Half Wave Antenna.

There are many more which I am yet to learn and try out and you will
certainly learn from the posts on this group with many experts.

I chose a previous version as it was cheaper and my friend told me that it
is enough for my type of basic use. It was bought from another VU ham's
online store.

I was also confused like you for about two years and kept looking for a
reliable source till my friend recommended one after he had used it.

Please note that it is a very delicate piece of equipment to be used with
extreme care. Some have lost it by inadvertently transmitting while NanoVNA
is connected to another nearby antenna.

Make certain that you are buying a genuine nanoVNA and not a knockoff. The list of approved vendors can be found here...

NanoVNA.com is the place to go to about your new VNA.

if not going above 900 mhz , get the nano h4, get from randl electronics, it will NOT be a clone.

If you are going to be doing outdoor work, I strongly recommend the H4 with
it's 4" screen. It is extremely difficult to distinguish between a slash
zero and an 8 in bright light.
Also, the H4 shows the stimulus range for each saved band, which is a big
help.

Most hams are happy with the -H4.

Forgot to mention that I have the H4 version and I am very happy with it.

I'll second Dave's recommendation. The least expensive option. If you must go above 900MHz your costs go way up for the higher end models. I'm very happy with my H4

I use a micro SD card to save calibration settings.

It is also very easy to damage ANY instrument by connecting a charged cable to one of its inputs. A cable can pick up a charge from being flexed or from the internal friction of being unrolled; ungrounded antennas can be charged by wind currents. It is good practice to discharge all cables by momentarily shorting inner and outer conductors before mating them; often it is possible to do this using the outer conductor of the mating connector, coin, tweezers, etc.
