Actually, it seems remarkably low..

But not if you have to hang in a harness for 3 weeks, rassling a heavy
spool of wire and so forth.. Been there, done that, it isn't any fun after
the first few hours....   Rig a scaffold like window washers use with a
motorized winch.  Your insurance cover will require something like it
anyway.

There you go... you probably don't need huge diameter though.. I haven't
seen ACSR in small sizes (like AWG4-6), but that doesn't mean it doesn't
exist.

lower loss... Which is a flip answer, I realize..  Mostly, you need to do
some serious simulation and calculation work to establish the bounds of
your problem before you start down a path which is infeasible.

Actually, horizon distance, on level ground, approximately d = 1.2*sqrt(h),
d in mi, h in feet,  So a you could see the TOP of a 100 foot high tower
from 12-15 miles away..(depending on how high the observer is...)

You should see it when you make a big fire vortex (try 5 gallons of
gasoline in a puddle on the ground..) (DONT TRY THIS AT HOME...!! or if
there is any wind at all!!)
