The feedpoint choke
is wound on a #43 core (I think), which may make it a bit more
credible.
Very wrong core for HF and 6M. #31 is the only good choice.
The measured minimum SWR is 2.2 at 1925 KHz, and resonance (X
crossing zero) is at 1983 KHz. All measurements made at the base of the
antenna
Now here's the part I *really* don't understand - at X=0, the R measures
119 ohms.
The value at X=0 doesn't make sense to me either. Lower SWR at 1925 does.
I suggest that you do an impedance to display the impedance, not SWR. If
your analyzer can't do it, borrow one that can.
