I see there are a few here who purchased a low(er) end VNA to do basic antenna measurements - being a gadget collector, I happen to have a couple (soon to be 3, more on that later) and I’ve always been curious how they stack up against each other. Unfortunately, I don’t have a “real” VNA to pit these units against, but some data is better than none in my opinion.
I took measurements of two antenna I use for 978Mhz:
Flightaware 978 66cm antenna:
And a Netgear ANT2409 (Meant for Wifi):
Top: MiniVNA Tiny+ (Chinese clone): ~$300
Bottom: N1201SA: ~$150
As you can see, both are very, very close in pretty much every aspect. I realize the markers aren’t exact, but can’t set a custom marker (that I know of) in vna/J which is the software the MiniVNA Tiny uses, but I used the same marker on both VNA’s for comparison purposes.
I’ll follow up in this thread with more tests (probably some 1090Mhz antenna for good measure) since I have the new NanoVNA v2 (version with battery) on order:
I’ll be very interested to see how the $60 VNA stacks up against these two.
Overall, I don’t think a person could go wrong with either of these units - we’ll see how the $60 NanoVNA v2 stacks up soon.
EDIT: I would like to add that I’d rather see people support the original creator/manufacturer of the products, namely in this case the NanoVNA v2. Unfortunately none were available from the creator when I ordered, so I went the AliExpress route due to lack of patience. For those looking to purchase, I’d recommend looking at the following. I do not know if the quality of what I end up receiving will be comparable:
