Re: Purchase of V2 from R & L Electronics
Many thanks David. Your link does take me to a V2 group with posting this month although not on the subject I seek. Some group identity confusion. I was already subscribed to a V2 group (groups.io)

There was a post in the V2 group on 2022-Jun-16, so you may want to check that... /g/NanoVNAV2/message/3411 David GM8ARV -- SatSignal Software - Quality software for you Web:

Purchase of V2 from R & L Electronics
I am totally new to Nano VNA and earning. Was planning to purchase a NanoVNASAA2N from R & L Electronics. Then I discovered that Tindie seems to be the "official" source of the V2's etc. Would

Re: Measure a single wire (not coax) for frequency
.. Here are 2 pictures from my measurements - one with grounded nanovna during the measurement with a length of stranded wire put into S11, the second with nanovna not grounded. You may see the

Re: Measure a single wire (not coax) for frequency
Yes, nanovna will show you the resonance peaks in form of max |Z| in case of EFHW antenna pretty well (see the picture in my previous post). I did it many times with various EFHW antennas. Simply put

Re: Measure a single wire (not coax) for frequency
I thought this was a fair question, so I tried it. I laid out about 8 ft of stranded wire about 16-18 AWG. Poked a few strands into a female SMA coupling. Connected that to about 4' of RG-316, which

Mark, Great news! The person that put that document together did a phenomenal job.I think the name "beginners Guide" may deter many who are in fact very knowledgeable?to perhaps assume the document

Re: Measure a single wire (not coax) for frequency
Your antenna works because the radio metal case, power cord and the shield of any accessories connected to the radio are acting as a counterpoise. You don't have a free space antenna setup. Mike N2MS

Re: Measure a single wire (not coax) for frequency
Measuring Return Loss means you are sending power to something and measuring the power returning back to the source. Then the calculation can be made. You can't calculate RL to a single wire just

Re: Measure a single wire (not coax) for frequency
I'm not building an antenna. All I want to know is if the NanoVNA can show me return loss peaks with a single length of stranded wire. Nothing more. I have an antenna and it works just fine. Don't

Re: #hardware #hardware
I have to thank you for the good advice. Even though I'm not a newbie, this was a great resource that told me where to find things. My device is the PCB-sandwich type, I downloaded edy555's build from

Re: Measure a single wire (not coax) for frequency
Or, more to the point, it _may_ radiate in some manner, because any end-fed wire will find _something_ to act as the image antenna, whether that something is intentional or not. Whether or not the

Re: Measure a single wire (not coax) for frequency
Yes, the NANOVNAs are capable of making these measurements. HOWEVER, and that's a huge "however", the chassis of the NANOVNA needs to supply the other portion of the wire. An end fed is only half the

Re: Measure a single wire (not coax) for frequency
Sure they were!? Those big taped coils in the transmitter outputs became antenna loading coils. You could say the antenna by itself wasn't resonate, but the transmitter-antenna system was. (Well,

Re: Measure a single wire (not coax) for frequency
Hi Fred How do you feed that 80m loop?? 1:1? 1:2? 1:4? Or monoband with a quarterwave 75ohm line and a 1:1 balun or current choke?? So.. I fact you can measure your loop... If you messure on a coax

Re: Measure a single wire (not coax) for frequency
Their antennas were NOT resonant! But they kept trying different things until they got their signals heard where they wanted. They learned as they went along. Just like my first lousy 80 meter

Re: Measure a single wire (not coax) for frequency
They put an amp meter between the transmitter and the antenna. Adjusted for MAX AMPS! The output circuit has lots of taps and variable caps.Could be adjusted over a wide impedance range.50 Ohms was

Re: Measure a single wire (not coax) for frequency
Real world. Interesting. If Hertz and Marconi stayed in the real world, would we have what we have now? So, if the tool we have won't work, fine. I understand that. I have seen where random lengths of

Re: Measure a single wire (not coax) for frequency
Brian, to measure the resonances of that single wire, you need to extend it straight in clear air, far from any objects, connect it to the center pin of the NanoVNA's port, and connect the shell to an

Re: Measure a single wire (not coax) for frequency
Good morning Mikki from Atlanta Ga. I have a question for you regarding the length of this wire. I have this full wave 80m loop up in the air and would like to measure it and see where the resonant
