I'm used to the old Tek pulse type TDRs. What would be the effect on
the trace of a swept frequency TDR
with FFT when the line is terminated with an antenna with several
resonant points,
I don't have a good answer to that. I do know that both my Ten Tec TAPR
VNA and the DG8SAQ VNA can provide a good TDR that sees a lot of detail
on the line with an antenna attached, and I think the AIM units can
too. I've also seen what I think are reflections from antenna elements
and from the earth, but might be "wraparound" in the FFT.
