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. 73, Gary W2CS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
