[TowerTalk] Getting a stuck wire antenna out of a tree

[David Robbins]

Lets see-saw...
1. chain saw
2. pole saw
3. saw attached to a drone... (have you seen the video of them trimming trees on a power line right of way from a helicopter?  Nasty!)
4. saw(or wire cutter) on a wire crawler that climbs the wire and cuts it at the top thus falling to an early death.  Something like this: https://spectrum.ieee.org/automaton/robotics/industrial-robots/georgia-tech-tarzan-robot-swings-around-on-wires
5. a wire saw (thin survival saw that coils up) tie long ropes on each side of it and put it over the problem wire.  pull the problem wire out as far as you can, even if you have to add rope to it to get the wire saw as high as possible.  Use the ropes on the wire saw to slide it up as far into the tree as you can, then use a sawing motion with the two ropes to cut the wire.  depending on how high it is you could thread the problem wire through pvc conduit and keep adding sections to push the wire saw as far up as you can before cutting.

Subject: [TowerTalk] Getting a stuck wire antenna out of a tree

I have one element of my 80 M 4-square stuck in a tree and I can’t get it down even with trying a variety of methods.  I believe that the element is not actually stuck but rather the 3/16” rope that it is attached to is caught in the notch of a branch and the branch may have grown around it and trapped it within.

I could try to pull it out with extreme force but I fear that the element would break and then leave a dangling piece of wire of indeterminate length that could couple to one of the elements and affect the pattern and/or tangle with the replacement element.

Does any one have any ideas of what else I might try to get the element out whole?

Tnx & 73
