I have 600 feet of 450 ohm OWL to my 160 meter transmit vertical.
I used to have 1000 feet of it coming from my old shack location that
was farther away.  4 AWG stranded THHW aluminum on 5 inch centers
suspended every 25 feet.  No intermediate spacers.  0.1 dB loss
at 1.8 MHz including the 50 ohm unbalanced to 450 ohm balanced
transformers at the ends.  I wouldn't say it was all that inconvenient
in my situation where it goes in a straight line.  "Someday" I
am planning to replace it with some 7/8 inch hardline I got for
nothing.
