Have a couple other drivers interested in what I’ve tried, this subject being one of them.
High performance mobile CB a handy description.
They’ve also found that once experienced there’s no going back.
The antithesis is that many drivers don’t want a set of ears that’ll clarify distant
Skip.
— I see “Coax Filter” as a subject might interest them nonetheless.
Local noise.
Dalhart, Texas a place not on the mental map of 80-90% or more.
Yet (like Cushing, OK) it is a location integral to what they consider their comforts and well-being.
The container & coal trains which pass thru Dalhart E-W and N-S are mirrored by meat & dairy highway transport also to the four compass points.
Rolled into town pre-dawn and was struck by how much louder are the LED traffic devices without feedpoint chokes.
The Plains may be CB nirvana, but it’s not without challenges.
The man one wants to hear is gonna fade out faster at these important junctions as but 5% of Americans are in The Great Desert he’s much harder to find.
FT240-61 on a jumper ain’t gonna kill anyone’s paycheck that week.
Or wind them in at both ends.
You need to turn your brain off for a second. You don't have any clue what you're talking about.
The NanoVNA has been around for years and you likely will never need to update it. I can't say for certain but it's doubtful. The current firmware is very stable.
There's no PC or any other device needed. It's a standalone device. You might want to watch a few videos.
Here's a good starter video:
Some of the videos are frankly quite poor. Smith charts are not user friendly and turn people off -- you don't have to use them. It's just the default viewing mode. Watch the above video and you'll get it. The device is super simple to use. I can't tell you how much you'll learn from just using this device. It's far more interesting than an over-priced antenna analyzer.
FWIW, here's a NanoVNA video showing live tuning using the smith chart:
BTW, here's what I was thinking of. I thought I had linked it before:

For what you're doing you don't need the more expensive model.
I see you’re recipient of a degree in diplomacy same school as I.
No need to talk past each other (where we’re starting to go).
Thanks for links and detail. (Sincerely). I’ll enjoy going thru. Glad for it as thread addition (add more as it occurs to you).
Market for these is bewildering, and constant updates & revisions is a turn-off.
Features a distinct appeal. I don’t find the idea of learning to use a Smith Chart daunting, instead
I am irritated by “tech” supposedly makes it easy and doesn’t (glitches, not hardy, needs update).
These NANOVNA have been throwaway devices
in main. That’s evident.
It’s not “ability”, it’s
reliability.
Radios — in my world — suffer enough insult.
But are hardy, generally (given tech access for problems).
Others in my shoes may be more comfortable with NANOVNA,
I’m not.
Rig Expert has a track record in big truck world. Not as much as stone-age MFJ-259, but both seem to last.
Had I the luxury of a home station (someday) and was in my pickup more often (someday), it’d be more attractive. I’m in this big truck 300-days/year and am simply tired of tail-chasing big truck mobile antenna problems.
Making a random stop to help another hand is foreseen.
Quick & dirty as may be to get him a baseline. (Bad weather and tired men).
There’s no leisure in this. There’s next-to-no-one I’ve found cutting trail out ahead. We’re all at work. Or trying to keep up with what’s at home.
In this world, if you’re awake, you’re at work. It’s that simple.
$260 vs $130 isn’t a value question seen from my viewpoint.
Features don’t trump hardiness.
When it was $360 vs $90, it looked better (throwaway).
There are those more inclined to circuitry than I in this
visibly invisible world of truck driving
. Any luck and I’ll someday run into a driver will hook up his latest device to my system with better intuition.
My strengths are elsewhere.
In this field it’s perseverance I’m given.
Half a handhold.
You remember this you ever wander into my world thinking you already know a little something. (I don’t mean truck driving).
My end (my goal) is to have provided a model for others.
A reference. I’m not expert, nor will I be. To use the parlance of our world,
hey, I’m just a dumb truck driver, do with it what you will.
“Coax Filter” a subject unknown or ignored. Tying that to the larger plan is context (tuning).
Emotional resistance is huge.
Thats the gist of things.
A model (the guy who tried X).
