Serious question
Doubting the accuracy of my NanoVNA H4. Is there a way for a non electronics minded person to verify the accuracy of my H4? I am a beginner with the NanoVNA. I have calibrated the unit per

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
I have two 259 variants and will probably keep both of them. They are a good tool for the primary job intended, and are arguably a better solution for non-technical hams who don't want to be bothered

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
While I appreciate and respect all the opinions here, I feel the need to reply.
I have owned MFJ-259 and nanoVNA and can say without question that the nano is far superior in every way that is

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
The NanoVNA and the MFJ AA are directed to 2 different groups of people.
The MFJ is more of an entry level testing device that take care of checking
an antenna in a fast and simple way, like using a

Re: Has OneOfEleven gone again?
You are being kind here Radu ;-)
As my name can hint a bit at my original language, you can figure that I
learned english later in my life.
I also found that english can be dry. But it is not the

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
Yes, tuning in the "design a matching network" sense - which is why I think it's more a design tool - you look at the smith chart, figure out what components/networks will make it work.
That's

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
Well, Jim, I'm a total nerd when it comes to RF and the HP 8753C. And,
yes, I've tuned / adjusted antennas using only the Smith Chart. Those were
antennas aimed at UHF and the Hi line at 1420 MHz

Re: Has OneOfEleven gone again?
Likely a language barrier issue. English is a very dry, down to facts,
goal-oriented language; it can sound a bit abrasive to non-native speakers
(especially romance languages ones). I happen to know

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
It really addresses a totally different need. The MFJ is a handy device - Having a meter needle/LCD display to see the "dip" at resonance is a pretty fast way to trim a dipole.

I believe that the subject of the post is
the issue although I don't see anything
wrong with it either.

Re: Has OneOfEleven gone again?
I wondered the same thing myself.
The 404 may have been glitch at github or maybe a mistyping of the url but I didn't think it was terribly disrespectful to ask about it.
But maybe we are missing

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
I used to have an MFJ-259. Errors and misreadings were common, especially
at the extremes of frequency ranges. Also, tolerance on readings were
about 20% or worse - bad...... And MFJ misleads on

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
OneOfEleven,
Any objective reading would infer the "glee" over MFJ being "peed-off." They're not. And...sales do not seem to be hurt much as they can't keep up manufacturing production of their

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
Carson,
Read any manual for a MFJ A-A..you'll see the section on calibration. MFJ sells calibration sets for their MFJ259/269 A-As.
