[Elecraft] KX3 remote transmitting

[Ron D'Eau Claire]

That's how the commercial HF stations did it. Keep in mind they used real
ladder line and NOT "window line" that is frequently mislabeled "ladder
line". 

True ladder line has large diameter conductors (usually No. 12 or larger
wires) and only enough insulator bars separating them to keep the wires
stable. That's compared to the window line that has a brown (polyethylene I
believe) web between two much smaller wires with openings (windows) cut into
the webbing. 

Window line works reasonably well, but does not have the stability and low
losses of true ladder line, especially for long runs. One of its biggest
drawbacks is that moisture, ice, snow, etc., can change its characteristics
appreciably in spite of the windows. Ladder line does not suffer such
changes unless it's buried in snow or iced over.

Years ago I worked a chap ( maybe in Wyoming or Montana ) in a similar QTH.
He had built an "open wire" line suspended on posts with fencing insulators,
every so far, to keep the lines taut in the breeze, over a huge distance . .
can't recall for sure, but I think it could have been up a steep slope as
much as a mile to find clear horizons. Baluns at both ends of the twin
feeders . . I think there was more going on there, that is, switching of
different antennas, rotators, etc. but it certainly worked. Not a small
project I would say.
