I am getting used to using NanoVNA which arrived a few days ago. I made many stupid mistakes in using it, and also asking many stupid questions, I feel I am getting to know it more day by day. The RF Demo Kit for NanoVNA was great help too.
Anyhow, now I am thinking of ways of using NonoVNA to analyse a 9:1 HF balun that I bought a few year ago. It is found in the drawer, but it doesn't say anything on the freq. range it covers. I recall it was definitely for HF bands. But would it cover MW and LW too? And upto what frequency does it cover?
So to simple put, would it be possible to find out the lower and upper limit of the frequency the balun covers with NanoVNA? If yes, then how would you do it?
