Dave,
One more thought: Years ago I put a 2-element quad on top of a 150' Douglas
fir, 800 feet uphill from my cabin in a canyon. I used 800' of open-wire
feeders that I built myself, in 100' lengths. I used #18 bare copper wire with
acrylic plastic spacers made of lengths of 1/4" diameter stock. I spaced the
wires 2 inches apart. I fashioned a 10 gauge wire substitute tip for my Weller
soldering iron, in the shape of a "Y". For each spacer, I heated the wire with
the Y and laid the spacer between the legs of the Y. The heat melted the
plastic and allowed me to embed the wire halfway through the spacer. I put
each 100' length under tension with the wires spaced 2" apart and worked my way
down the line, heating and placing spacers every foot or so. Once I had
fabricated eight 100' lengths, I spliced them together. Used TV standoff
insulators on trees to support the feedline and up the antenna tree. I spliced
on a 15 foot length of flexible high power twin lead to connect to the q
uad feedpoint. I tied all three (10-15-20M) feedpoints together at that
point. Had a 500W amp at the shack in the cabin and worked the world. After
windstorms I would occasionally need to hike the line and find a break where a
branch had hit it and repair it with a propane torch. This stayed up for 4
years. You might consider using the open wire feeder between your shack and
the distant antennas with high power baluns transitioning to coax at each end.

I would like to thank everyone for their comments...
I have enough data to review.
