This also works. As the tree sways back and forth, you don't want the
wire to keep moving. I brought the fixed end of the rope some distance
from the tree, and fastened it to half of a cinder block laying on the
ground. The cinder block will move to give you slack, but not move back
when the branch moves in the other direction.

Think FUSE. Choose your point of failure, don't let it happen.

A couple of decades ago, I experimented with the "cylinder" (don't know
the correct term for it) from a screen door. This is the device which
allows the door to be opened quickly and then to close slowly. There is
an adjustment on it which allows this action to be speeded/slowed. I
remember that I ended up with 3 or four in series. The final "fail
safe" was a weight which would move to prevent damage to the antenna.

It worked until I went on to other antennas ... I am surprised no
antenna manufacturer has designed a device more suitable but along the
same lines.
