And, here is where a DLM antenna is nice, keep the coils of low Q and
bandwidth is "surprisingly wide."

Yup,
My 160M antenna came at at a resistive 200 ohm plus resonance and with
a bit of fiddling
I now connect the coax direct and cover the whole band. Not sure if I
would have been better off with keeping the high resistive impedance
and using a transformer but snow is on the way so beggars can't be
choosers.
