I have heard many stations using G5RV and, for the most part, they don't have big signals.? My conclusion is that this antenna is not that great, certainly when compared to a resonant antenna. You

Is the antenna (the 135 ft length) positioned between 2 trees so not much of the antenna is being touched by the leaves or is the antenna laying on a tops of a couple trees so a lot of the antenna is

Bob Albert, thanks. What you say makes sense for the little I do know. It is a 9:1 matchbox. I have limited space and was trying to find an antenna to work all bands just by changing frequencies and

A 135' end fed half wave should be resonant somewhere in the vicinity of the 80 meter band (3.5 MHz). The exact resonance will depend on height above ground and the proximity of structures, among

First decide the frequency range of interest.? Then program it either as start and stop, or center and span.? Then set up for Smith chart and SWR display. The Smith chart will plot the impedance of

I can assure you the NANOVNA's agree quite well with equivalent measurements using the HP 8753C VNA - FAR more expensive!! It's a good instrument. Dave - W?LEV wrote:

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

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

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

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

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

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 for

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

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. (with all it's

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

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

See, a little love shared there. They say it makes the world go round Frank ;)

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 being
