Thanks for the responses. The nanoVNA I have now I managed to break the s11 connector off the circuit board but I did repair it successfully. Then I 3D printed an enclosure to help protect the

There's 20dB of attenuation between the external port and the mixer. More likely a overpower situation would blow up the resistors in the attenuator before it cooked the mixer. The series resistance

Bruce: You might have caused the AD602 devices to open, as they have almost zero protection, aside from a capacitive input. The level of R.F probably killed them. The devices are readily available,

Is it cold enough? Remember, the performance of an antenna is inversely proportional to the temperature at the time it was erected. 73, Zack

Thanks all for the valuable input. I will check into the modeling programs.

Thank you, Jean-Roger, for taking the time for an extensive answer! I had to lay down flat on my bed with this one ;) This response got long. I tried to get it all in there, not necessarily

Thank you Christian, for answering! Complex Scattering (including the impedance from S11) refers to all the S-parameters being calculated from readings of scattered current and voltage waves, being

Thank you for answering, David. This is also what I know and related to, with both the Impedance and Admittance having a Real and an Imaginary part. But Jean-Roger have got to the core here; The

tradition procrastination in antenna work is to continue until there is no choice by which point the weather /has/ become wet and windy! --

Also, ditch the S11 Phase display and the SWR display. You can add SWR lines on the S11 display. Add SWR = 1.5, 2.0 and 3.0 lines. You'll get larger, easier to read displays. 73, Carey WB4HXE

To get a far better idea of what is going, please use 10 segments instead of one. The present data is too disjointed to make any real conclusions. The segment setting is in the upper left of the

Hugen's company sold a bunch of H4s to Banggood back in the spring and that is where I got mine as it was actually cheaper than getting from R&L - and I'm in Canada. Go figure.? On Mon, 2 Nov

EDIT I got 100ft of RG8X coax today and a gas tube lightning arrest delivered today. I have added some more plots after doing some testing. First i plotted after just replacing the coax going from

My friend N8CDWCarl Has a few month old h4 new in the box with the gold lettering unopened never used I think he's looking to sell it I don't know how much he wanted I contacted him for info so I
