Re: Question on remote use of NanoVNA
Explaining the fundamentals takes time, practical example is more suitable for this audience.

Re: where is the end fed natural resonance
Sorry. Coming in late and haven't read all the response. FWIW: Resonance is when the impedance is purely resistive with no reactive component. That resistance can be anything but often falls in the

Re: Question on remote use of NanoVNA
Dragan, Personally if Dave believes this I'd like to hear his concern and sort it out myself. As a rule, I wouldn't shoot down anything as nonsense because of an individual result not being in my

Re: Question on remote use of NanoVNA
As stated I have the "H" not the H4. Is that still the case?

Re: Question on remote use of NanoVNA
And I think the question is really more about ¡°radiated emissions¡± or ¡°radiated susceptibility. So let¡¯s say you¡¯ve got your 100 mW 2.45 GHz Tx hanging off NanoVNA which in turn is hanging

Re: where is the end fed natural resonance
No idea, but if NASA buys something, the mfr sometimes says ¡°as used by NASA¡±. For all we know, someone bought one for the ham club at one of the centers. There¡¯s a somewhat famous story about a

Re: Question on remote use of NanoVNA
Typical home WiFi router outputs around 20dBm. Attach it to any of Nano inputs and see if you get any issues.

Re: where is the end fed natural resonance
How about the term counterpoise as a return? If the return is a wire or wires we can refer to it as radial(s)? I recall HF communications was tested on a Project Gemini Flight. I don't remember the

Can someone point me in the direction to find Nano VNA Saver for Windows 10 I cannot find it on github.com Thanks

Re: Question on remote use of NanoVNA
But the input of the NANOVNAs is wide open. Enough RF at any frequency into that port, and compression and false readings will occur. Dave - W?LEV wrote:

Re: where is the end fed natural resonance
Jim Lux, I just have a lot of trouble with RF energy and the term "ground". It's maligned in the amateur circles. There is no need for "ground" with RF fields, just a return. Please comment. Dave -

Re: where is the end fed natural resonance
ISS isn't using HF long wires, either. Most of its antennas are things like patches (which are a sort of end fed dipole) or horns (which have tiny monopoles in the feed point) possibly illuminating a

Re: Question on remote use of NanoVNA
I'd sort of agree. I've got my NanoVNA (which is the stacked bare board variety) sitting next to a WiFi access point putting out 100 mW, with no problems.
