Exactly! Mike, you could not be more correct. However
there is a downside to reducing wire size. The smaller
conductor will have greater DC resistance that will
translate into somewhat greater loss, but perhaps more
importantly, it will increase the inductive reactance
which has implications beyond requiring more capacitive
reactance to be in the feed.
This is why I contend that 3/8" galvanized guy cable
is a better choice for drape wires. Back in the day
(when copper was cheaper) slant wires were often bare
#6 stranded copper for very much the same reason.
