Hey David, ? ? Good morning. Everything looks pretty good, and I'm sure you've noted the points about calibrating at the antenna feedpoint.? When transmitting at low power, does your radio / SWR

** The easiest to interpret: yes But it is not the most relevant. In SWR you display 2 variables; in Smith you display 3. The SWR does not allow to adjust an antenna because, on the Smith, the minimum

** Yes, I understood what you did. It is not a mistake. You measure the impedance of your antenna, brought back by your cable. It is the impedance that your TX sees in transmission. Where it is a

Francois, I calibrated at the S1 port directly. Then I connected S1 to the feed line and subsequently the antenna. The plane I measured would be where the feed line attaches to the radio.

Hello Do not lose sight of the fact that the nanoVNA is a kind of measuring bridge that will indicate to you, among other things but above all, the impedance at the point where you did the OSL

You should calibrate as close to the reference plane you are wanting to test as possible. For an antenna that would typically be at the feed point. 73 de Dan AI5OL -- This email has been checked for

Thanks for asking! "did you calibrate with the coax used? (means short, open, load at the cable end) I calibrated by attaching the calibrants directly to the Nano VNA H. "looks like your antenna is a

did you calibrate with the coax used? (means short, open, load at the cable end) looks like your antenna is a bit on the long side no need to cut the ends .. just fold them over (cause if you hang it

Looks good. I also just got a nano and have not tried it yet. As a Ham, I am used to looking at VSWR sweep for antennas. It looks like you have not yet found the whole SWR dip, as the lowest SWR is at

You don't even have to consult the Smith Chart. The application has done that for you. To the left of the Smith Chart, the application has given you the following information for the three markers you

Fresh out of box. A sweep of my DIY 10M antenna... S1 - connected to 50' Rg58 via BNC connectors to my 10M dipole. The lowest piece of which is about 12' off of the ground. I set markers a L, M and H

I'm know looking at the connector. Some have a lever the needs to be moved to remove the cable. I don't see one, is the just a push in pull out ribbon? i.e. no moving of any levers to get the cable

Thanks to all Finally , I found this response on this topic : /g/nanovna-users/message/26386 73's Nizar

Make certain that there is nothing touching the screen (masking film remnants, mounting hardware) and interfering with your touch, loosening/removing the screws may be helpful. 73, Don N2VGU

All, We have reached our goal of raising another year's annual groups.io fee for this group. Thanks to everyone who contributed. I have to write that this was accomplished in less than 24 hours, which

Hi VA3RR Thanks a lot for the help. I conlude that MS5153 may be a little bit better to go up to 300Mhz lnstead of 290Mhz for SI5351A and also a little bit better for harmonics measurement with few db

Donated , thanks for the service Maurizio IZ1MDJ
