I think in today's parlance many use the term ladder line to mean any flavor
of non-coax, 2 conductor feedline.  I distinguish between ladder line
(insulated twin lead with holes) and open wire line (OWL) no insulating
material other than the occasional spacer.  Ceramic, plastic, etc.  The OWL
does not suffer from the dreaded detuning in the rain nearly to the extent
of ladder line.
