You should get some connector savers. They look like an attenuator but they have a straight through connection. Just wind them onto the two VNA ports and leave them there. No need to use jumpers that way.

I wound mine around a 1.25" pill bottle and put the SMA connector directly to the two inch long wires.  (no coax)  If I can connect it, I can replace it.  I used "liquid tape" to bind the two  turns and the two inch long lead into a rod.  I used about #20 enameled wire.  I use mine like a wand holding the MiniVNA-Pro with coil as a hand held probe.

Amazing results of the nanoVNA.  Thank you.

That $53.95 ad for a set of pick-up loops for an MFJ cracked me up! That's as much as an entire NanoVNA. Thanks for the videos. Some good hams, including you are turning into YouTube Elmers and creating a body of work that can teach hams of any level how to build, how to repair, how to design, even everything about atmospherics, or tips and tricks. And the info just grows continually. It's a wonderful thing. Now, if we could just get rid of some of the Baofeng unboxing videos. :)
Thank you.

This idea came from a magazine article years ago. MFJ copied it and sold it as an adaptor for their antenna analyzers.

It is actually better just to connect the trap or resonant circuit to the VNA directly and measure the impedance of the trap or resonant circuit. Just use a short jumper with a cable separation at the far end with alligator clips.  Calibrate that with an OSL calibration. The VNA can measure the actual trap impedance and Q using a direct connection, I do it every week for testing RF chokes.

You  don't have to spend $53 for a useless hunk of wire you can find in your junk box. You can make a jumper or adaptor for a jumper with clip leads and read the actual impedance with a direct connection.  It can do anything this can do and better, and you save almost $60!!

Inspired by this video, I did a few tests myself. I found that SWR was by far the most stable parameter to use on a wide bandwidth, like 5-100 mhz, and on a short bandwidth, like 10-20mhz, delay gave a very sharp dip. My pickup coil for 5-120 mhz is 5 turns at 40mm dia. for 100-450 mhz, I used 3 turns of 12mm dia.

Very nice. Skillfully done. I'll get one of those VNAs.

What was the nano vna set to? Phase, swr and log mag? Was out of focus so I couldn't,t read

Very cool 👍

Excellent video! Thanks

This Is Actually very Helpful, THANK YOU VERY MUCH FOR THE VIDEO AND INFORMATION!  
Greetings From Me !

I didn't know that that could be done with a Nano VNA. That was very interesting! 73's

👍Thanks for posting.

Superb!

This is great stuff!  Subscribed :-)

A very useful video and well explained, thank-you. I may well make one of these.

Thanks Rick, this was really useful. Could I ask, what would cause an LC circuit to have a greater or lesser effect?

Sweet!

Can you show the smith chart of this test please...to see resonance and any parasitic  values?Also how strong is the coupling needed- some grid dip instructions say the less the coupling, less energy loss and better accuracy of resonance freq.
Good demo.

please let us know how to setup the traces. Yellow trace is set to Phase, that's clear. But what about the blue and green traces?
