I supremely appreciate a woman with enough grit to have a lab and use a Field Expedient method to tension antenna wire with a Tractor in an old school configuration... That's Classy AF and If'in I Twern't married to my absolutely "Precious as Rubies" beautiful wife, then.... I'd be... um... Single.
It’s Wander Woman!!!Oh Wow ! Guys !
I had no idea when I posted this it would evolve so gloriously !
I should have prefaced at the outset that I am by no means an expert on this feedline- or any feedline, for that matter. My background with the G-Line goes back to the years when I would demonstrate them to undergrads, back when I was a TA. The extent of my understand'ng is pretty much detailed in what I have already said. But I can fill in a few details.
The wire was ( yes past tense now- more on this to follow )-- was a special find that the guys in the machine shop located for me. It was a thousand foot spool of number ten copperweld wire, coat'd with an epoxy resin. What this wire was originally intended for -who knew-- but all I was looking for was that it be 'insulated'--- and I settled for the epoxy which worked fine, though I had used vinyl covered wires in my teaching days.
There was no intermediate support for the wire- it ran quite vertically from a barn roof- up to the top of the rock cliff that over shadows my place-- in one big swoop. I never figured it would last and the last storm proved the point -- but what is the old ham saying ?
If your antenna stay'd up all winter it wasn't big enuff
In the end, this was an experiment that worked. Anyone wishing to follow I hope will be as rewarded as I was.

Oh----and an Epilogue
One of my nieces is visiting over her Spring Break.
She and my friend Cindy were going off skiing--
We've had a couple of fresh snow's since the G-Line disaster--
New snow was covering the detached barn horn--
Some one back'd her F250 over--
...........well, you can fill in the blank
That horn is now flatter than a day old glass of Coke.
Spring will not see it re-strung. I have this idea about using a passive repeater instead.
Stay tuned !

It acts more like a resonant cavity (schumann resonance), if it wasn't oblong but a long cylinder instead, ti could work like a waveguide.
It's been a wonderful discussion, one of the best on radio reference.Oh Wow ! Guys !

--- a periscope is more like for microwave; a non resonant big mirror in effect.
I was thinking of something like that in NJ where I was in a fringe area, I could get a cell phone signal on the second floor, but not on the first... A really good beam or even a small parabola on the second floor, connected with coax, feeding a cellphone antenna on the first floor near where I needed a signal.Not exactly Joel,
What I envision are resonant beam antennas-- one (or more) turned downward towards the house- other(s) off into the valley, They would be hooked back to back with a run of coax. I'll use a beam at the house pointed towards this array to feed it-- All this, "passively repeating" a signal over my cliff.
Years ago I hiked up to the top of Mt. Davidson, the tall mountain that overshadows the old mining town of Virginia City, Nevada, Besides the awesome view of the snowy Sierras that extend from as far north, down to the south --as far as you can see, there were plenty of flag poles and mounments placed by Virginia City's Victorian era citizens--- but also up there were remains of a bizarre antenna system.
What I stumbled upon were several television antennas- standard household beam antenna popular in the pre cable/satellite days of terrestrial analog broadcasting, pointing off to the west (and the city of Reno.) Attached to these beams by runs of open wire feed line were what I can only describe as panels of chicken wire fencing. These were large 'panels' of wood (insulating them from the ground ?) overlooking Virginia City.
Cool !--- a passive form of a television repeater. Virginia City was certainly a fringe location masked by this mountain.
Later I ask a old Virginia City resident what they knew about those antennas up on Mt. Davidson.
"Some guys put them up there years ago when TV here was all snowy... we didn't have any cable or anything-- just the antennas on our houses."
"When we pointed our own antennas towards the mountain's summit the pictures clear'd up-- a lot"
So, there long ago was planted the seed of what will be a Spring time experiment (?)-- Maybe by May the snow will be gone and we can get up the escarpment ----

I thought Gonset was a radio manufacturer?This will blow your mind:
The other G Line; Gonset Line:
More:
Not very sure about this, but I'm thinking that reviewing the purpose of the thick insulators purpose on the G-line is appropriate.
You could put up some advertising billboards with aluminum foil backing. That might be large enough for a passive reflector.Not exactly Joel,

your familiar white alice system. It should get the job done.
ago I visited several de-activated White Alice sites and marveled at their engineering-- I think I even post'd somethings about them here in the Forums.....
