Does the nanoVNA have a TDR function? For some reason I thought it did, but I can't find it in the menu. Zack W9SZ <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-em

The minimum frequency of the SAA2 is listed as 50 kHz. The minimum of the H4 is listed as 10 kHz. It doesn't look like it will work. You might squeeze in the upper edge of your range with the H4, but

There may be a way to use the NaoVNA as a spectrum analyzer, but I don't think you can get an absolute measurement of the signal strengths like you can with the TinySA. You can get relative measuremen

It really is the wrong hardware for that. Get a TinySA. I have one of the original TinySA's plus a TinySA Ultra (which goes up to at least 10 GHz). I got my NanoVNA and both TinySA's from R & L Electr

I got a right angle SMA connector that RG-316 typically solders into. I ran a wire about 3 inches long through the opening to the SMA center pin and soldered it there. I ran another wire of the same l

Yes; in fact I had to do this to calibrate measurements made on a 1296 MHz bias tee using microstrip transmission lines. Zack W9SZ <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&

Exactly. I remember someone said in an article "While you've been worried about having exactly +7 dBm of LO to a mixer, someone down the street has 20 new grids worked with an unknown mixer level to a

It's not going to have much of an effect that is different than being over soil. The effect would be slight enough that you'd never notice it. Someone spent quite a bit of time preparing this article.

I have both a NanoVNA and a RigExpert AA-600. Each has features that the other doesn't. The NanoVNA is a two-port device and can be used to adjust various adjustable filters and tunable preamps. I hav

I've used it at 12 GHz. I don't expect the power level measurement to be accurate, but it's useful to measure relative power (such as peaking a filter) up to that frequency. Zack W9SZ <https://www.ava

I wish he had done each toroid individually to show what the range of each was. Maybe I'll do that. Zack W9SZ yahoo.ca@groups.io> wrote: <http://www.avg.com/email-signature?utm_medium=email&utm_source

The same cable was used for all the various antennas. The only one that didn't work was the 150 kHz one. All the antennas were constructed identically, the only difference being values of tuning capac

Why? The useful range of 31 material is listed as 1 to 10 MHz. The useful range of 43 material is listed as 2 to 50 MHz. It seems if you put the two in series, you're just making a great attenuator. Z

I had something happen the other day where the NanoVNA became a priceless instrument to at least show up the problem. I was doing some measurements that involve small antennas lowered about 350 feet d

I have stacked identical toroids to handle more power. I've never tried stacking toroids with different parameters. I suspect the AL value will be much different than that of either of the individual

Not at all. I am just noting it for the original poster. Zack W9SZ <d.milivojevic@...> wrote: <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-emai

If there are helical filters, just solder a line of small coax (I use RG-178) to one end of the helical filter and another to the opposite end. I would adjust the filter with the power to the radio tu

NOTE I have found that the capacitance varies considerably with frequency when measured with the NanoVNA. I would choose the displayed value around the frequency where you plan on using them. Zack W9S

It depends on what you want to do. Both the NanoVNA and some antenna analyzers do things the other doesn't. The NanoVNA can be used for a wide range of functions an antenna analyzer can't do. I also h

Actually, a dipole's impedance varies with height. You often see the curve I've attached. Even that can vary, as ground conductivity is also a factor and varies. Zack W9SZ <http://www.avg.com/email-si
