NanoVNA, CB and R & L Electronics

For those of you who don't know what a NanoVNA is, it is a "Network Analyzer" that is useful for checking antenna SWR, analyzing other antenna attributes, checking coax cable loss, and a variety of other things I don't know about yet. Though I bought it to get my home base/truck CB antennas dialed in, I suspect it will be extremely useful in debugging anything electronics or cable related. There are two versions, a 2.8" screen for around $50 and a 4.3" screen, the larger screen varies in price, $89-$119.



I have been trying for a week to get one and have been through two Fleabay sellers. They claim the item is in say, Los Angeles and what they do is get a tracking number so you can't cancel the shipment and you wait for a week or so or more. <rant>If I'd wanted to order from China and wait, I would have!</rant> As of today I'm still waiting and plan to cancel this one:



Additionally, there are tons of clones out there and the people selling them on Fleabay or Amazon are probably selling China clones. If you're interested I found a REAL U.S. Seller that guarantees these are the real deal.

R & L Electronics, Ohio

Having already tried twice, I called them, they also have a textable phone. He assured me yes, he has them in the store. There are two versions, a 2.8" screen and a 4.3" screen. I'd gone through so much grief over this thing I went with the big one, with shipping $110.

Have a look at R & L's Store here, video posted by the Ham Radio 2.0 channel, 5 days ago as of this thread:

I ordered today and he says it will go out tomorrow. Most of you know how gratifying it is to contact someone who actually picks up the phone and knows what he's selling. If not for the cold I wish I lived in Ohio, I'd be in his store daily (to my wife's chagrin.)

Using the NanoVNA to check SWR

 

A NanoVNA is very handy for checking antennas and cables. I like mine. YouTube will be your friend on getting the most out of it.

 

Thanks, do you know if yours is authentic or a clone? I only ask because I was gunshy about the clones, NanoVNA warns against the but they probably work as well as the authentic ones. You know, OEM vs Autozone aftermarket. :-D

 

Mine’s authentic. I’ve had it for several years.

Oh nice! Do you have an stl file you could share?

 

It's here, on thingiverse too I think. I use Blender and had to install an add-on to import the 3MF files. Good thing too I had to break apart the pieces. I have an Ender V3 and it doesn't do multi filaments, but it would be really good on a higher end printer.

If what's there doesn't work I can upload the .stl's in a zip.
