Default Window line billowing in the wind

But I'm thinking... if I just used two conductors of #16 copperweld
and some spacers to get true ladder line as opposed to window line,
would this billowing completely disappear, or drop to a tiny tiny
fraction of what it is now? Or would it just continue billowing the
same way?


The billowing depends upon the total surface area exposed
to the wind. It is akin to the wind loading specs for an
antenna. The way I solved the problem with 440 ohm ladder-
line (actually measured 380 ohms) is to buy The Wireman's
#14 stranded copper-clad steel, ladder-line product code
#554. With proper strain relief, that stuff is virtually
indestructible. It even put dents in my wire cutters. :-(
