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.

Re: Has OneOfEleven gone again?
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.

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
I would have to say the NanoVNA is probably putting a hurt on MFJ's sales of analyzers.

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
OneOfEleven,
I can say for certain that Martin Jue is not peed-off, as you put it, over the NanoVNA. He's been designing the next generation of the MFJ antenna analyzer line for the past two years.

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
Hi Carson
Well, knowing what I know about the NanoVNA's, I'd rather trust one rather than an analogue meter like the MFJ's, not because the MFJ's don't work (because they do!) but because a VNA gets

Re: NanoVNA vs. MFJ-259B Antenna Analyzer
Thanks for sharing this - I just joined this group today!
I had heard several times how the NanoVNA wasn't that accurate, so I was surprised to see how it compared to the MFJ analyzer. Thanks for

Re: Definition of resonance
Yes, this has been a good learning exercise. Remember that I made the test-setup to intentionally get some weird results to see if those could be handled by an antenna tuner and describe how. And yes,
