When using a NanoVNA to measure SWR on a multi-element antenna, with different length elements but all fed from the same feedpoint, which element’s swr is the Nanvna displaying data for?

I did made two remeasures - one with open end and one with shorted end. They are within 300 mm from each other... Which one is "closer to reality " ? Since the TDR graph did identify the coax type it

Newbie here. I am interested in testing antennas for resonance and swr. 80m to 70cm. Both indoors and outdoors. I was thinking of buying an entry level antenna analyzer. Several helpful people suggest

I am getting an "ERROR during sweep" message when using NanoVNA Saver version 0.3.9. The message states "failed reading data 1 10 times, Data outside expected valid ranges, or in an unexpected format.

I see updates, patches and fixes in the github repository as recently as 3 weeks ago for Nanovnasaver.

I have been trying to tune some ferrite rod antennas to a specific frequency. The target frequency is 530 kHz, and for reasons that may be too complicated to describe here, I want to use a fixed capac

I would like to see both S11 (SWR) and |S11| (Impedance) in same graph . Can that be done ? PS Because of recent experience in this forum I feel I need to state this - please force yourself to simply

Hello I appeal to your wisdom. It's on the sidelines of nanoVNA but some participants in this forum seem to me to know a lot of things, which is not the case everywhere With a circuit as attached 2F-0

Per message #32856... When I initiated this discussion, I did not measure the characteristic impedance of coaxial lines but those of twisted parallel lines that I use to study RUTHROFF transformers. T

I asked Google Bard about the NanoVNA. Here's its response. Brian

I've measured R+jX for a common mode choke with my NanoVNA H4 and would like to calculate the equivalent parallel circuit (RLC). Can this be done, if so how please? -- Mike
