How did you fix the rope to the guy wire?
Did you leave it there?
I forgot if I posted the entire story elsewhere, it has been a few years. But long story short. My friend (who jumped before me) grabbed the rope and climbed the antenna. He threw the rope to me. We tied off the end about 40 feet above me on the A, and the other end (mid-rope) to my harness. That way if the canopy slipped off, I would have a swing into the A, not a plummet to the ground. We tied it about 40 feet up so the swing would be slower should I swing into the A. Once that safety was tied, we could take some addtional risks to make the evenutal fall into the A safer. FYI, the A was covered in ice and the way the canopy was on the A, even the best climber would have struggled to climb the lines and somehow grab the wire as the canopy covered about 10 feet of the wire above my head and only one or two lines were holding my weight. Plus, I am not that good.

And since I had no other equipment other than a rope too short to get to the ground, and my home was hours away, and the ACE hardware store was closed, a rope fall into the A was pretty much the only non-fire department option.
Because I had a 180 on deployment and hit the wire while turning on rears, I was only about 30 feet from the A.
I threw the remaining rope back to the A, the other jumper grabbed it. We used it to pull me closer to the A, so my canopy was no longer above me, but to the side of me and almost below me. The purpose was to get me closer to the A for the next step.
I cut away one side of my canopy so I could turn my body towards the A. Then I carefully cut away the other side and took the fall into the A. The rope was tied off twice so it was more redundant than a rock climbing fall on a single rope, but still I had no clue how fast I would swing and if the first rope failed that was tied above me, the secondary fall on the other rope would have been hard since it was tied much lower. Only injury was a metal plate to my balls and sweaty skin that immediately froze to the A. The other jumper's hand, due to a lost glove, suffered frostbite.
Because it was well below freezing and at night, the cold blood previously cut off in my legs by my harness suddenly rushed to my body. The way I was tied off was against the angles in which a harness is comfortable, so the straps dug into my body all over the place cutting off circulation. I lost a lot of control of body movement due to hypothermia type issues, but was able to climb down, but could barely walk until I warmed up. By barely walk, I mean the land-owner who came to watch us asked me if I was so happy to be on the ground I was kissing it. I informed him that kissing the ground was completely unintentional and I was going to be crawling to my car. I warmed up in his car instead. This is something to remember if you ever rescue someone hanging from a harness for a while - the blood flow in their legs could be cut off and cause issues should it rush back into their body cold.
So then we went back hours later and got the canopy with a very big rescue pulley and some good old fashion rigging work.
Using that pulley and learning about the physics of rope rescue on an A - I designed what I felt was the perfect rescue kit for "the next time"...
1) A large pulley that can clip on a wire available from rigging suppliers.
2) A short rope (about twice the length of the lineset on a canopy) to hook to that pulley to drop to the jumper.
3) A longer rope to tie to the pulley to be able to belay the pulley down the wire to the jumper, and eventually be able to pull the jumper up the wire to the A.
Procedure:
1) Install pulley on wire, lower to jumper with rope.
2) Jumper ties to rope dangling from pulley.
3) Jumper cuts away.
4) Rescuer has the rope tied to their harness and down-climbs the A using their own weight to pull the pulley with jumper up the wire. Depending on the type of materials to make the A (round pipes vs angle iron) - a second pulley might be required at the A so the rope can take the bend friction free. If the guy wire is at a shallow angle, they might not need to downclimb, although downclimbing seemed to work very well.
5) Once the jumper is pulled back to the A, the jumper climbs back up the A to the wire and pulley, reties off to the pulley, and is lowered back to their canopy. Retrieves canopy, repeat procedures to get them back to the A.
If the jumper is not hurt, and is physically able, they can climb the rope to the pulley on the wire and get their canopy off without being pulled back to the A. Perhaps you equip that rope with hardware to allow a rope ascend. This is not part of my plan because getting the canopy off is not nearly as important as getting the jumper off, and climbing a rope suspended from a guy wire has risks.
P.S. The pulley system has been fully tested as we used it and procedures very similar to this to retrieve my canopy. If I had it on site when I jumped, I would not have had to take a fall into the A.
