Re: NanoVNA vs. MFJ-259B Antenna Analyzer

Brandon Parker
 

Sorry but that's not the case man. Don't get me wrong it's useful. But my
ability to understand it' is not the issue. My issues with it are the lack
of morals by the people that sold it. I have a certain disgust with the
whole idea of it because the bad luck I've had buying them. And the lack of
support from the crooked sellers. If I have to worry that bad about whether
I'm gonna get a functional unit or not... "so far two out of two were junk"
I managed to repair one of them and I use it for building transistor
circuits. So again I know how to use it. But to say it does more that's not
true. It doesn't do the fault finding in coax the same. That alone is a
feature I'd gladly pay for. And I just prefer the ruggedness of the mfj.
I'm sure with time I'll revisit it. And I'm gonna ask folks on here about
where the right place to buy it is as in who are the reputable sellers. I
think I may have just been getting out some frstration with the situation.
I guess I bought the mfj because I KNOW it will work and it will come with
the correct parts. The situation with the nano vna actually caused me
problems with not getting a larger amplifier out on time. And the mfj makes
it so easy to tune output coils. It generates all the info I need to do my
job where as the nano vna is all kinds of little screen and if you have
sausage fingers you gotta use the little stylus thjng. Or hook it to the
computer. I figure for that part the mfj is worth what I spent on it. All
frustration aside I will be looking around a little before I buy another
nano vna. Matter of fact.... What's the larger better ones if anyone
doesn't mind... I actually would grab one but I'd like to know where I
should purchase it from so I have better experience with it this time. Like
do you guys get em on ebay or is there some other outlet to buy them from?

Sorry you had that experience. Likely, you did not take the time to learn
how to use the NANOVNA!! It is a *FAR* more capable instrument than
anything MFJ offers at 4X the price, but it is not just an antenna analyzer
which the MFJ product is. The NANOVNA's are not great just for the price,
but for what they offer the user - IF, and only IF the user is willing to
learn how to use the instrument. It's no toy!!!!!!!

I own a Mano vna and I threw it in the toolbox and just paid the 360
bucks
for the mfj with the wall wart without hesitation. Nano vna is junk. I
have had nothing but problems. I've boughten two now and they were both
junk. The first one the person I bought it from got mad that I had put
the
wrong address and sent me a returned item that was broken. I gave up
claiming the replacement because the seller was obviously a pos that
hates
life. And tokk their own hatred out on me. When I was just another paying
customer. I needed it then and there and instead of just sending me a
good
one they told me to send it back and they would replace it. All set. Next
one had issues too from an entire different seller. Goes to show the
quality you can expect from a stupid 50 dollar pc of test equipment. Nope
I'll stick with the pros. And the fact is.... The Nano vna is used for
different things. It's good for circuit analysis. Like for my amplifiers
and testing my transformers impedance. But as far as big boy Jobs and
measuring inductance on my coils n such and my antenna tuning I'll stick
with the mfj. People only speak highly of the Nano vna because it's a
cheap
way out to KIND OF do the job. And I've seen soooooo many bad reviews of
bad experiences with buying the nano vna. It's hit or miss. You MIGHT
get a
fully functional unit. But your odds of getting screwed with a junk
one....
Are JUST as good. I'll spend the money and get what the PROS use. Forget
the nano vna
Just a cheap Chinese knock off type TOY

I just watched VE3OSO's comparison video and had a chuckled at the end
lol.

I've been thinking for a while just how peed off MFJ must be now that
we
have these extremely useful little VNA's, especially with how much they
cost. MFJ's sales must have taken a hit I should imagine.
