Folks

So I'm reading the 2006 ARRL Handbook page 22.6, There is a single
line stating "Steel wire is a poor conductor at RF; Avoid it." Any
idea why? Or is this just one of those physical properties?

So how much poorer than copper? Steel clothesline is easily obtained
and not that expensive. Admittedly though I haven't done much
research on copper or the other type of wires the Handbook mentions.
