I have built myself a rope ladder. It's about 7 meters long, made from 8mm polyester rope and beech rungs ~3cm in diameter, 35cm long. I drilled 1cm diameter holes about 25mm from each rung ends, rungs are supported by an 8-figure stopper knot below each rung.

Both side lines are separate, connected at the top to a carabiner. When deployed, the ladder is supported by a rope going over a suitable branch, anchored with a strap down near the ground.

Why would I need a rope ladder you say? To mount meshcore repeaters to trees of course!

First test next Monday.
