What is your concern? I use the same wire for temporary Beverage antennas
and twice in the last 10 years I had tree branches fall and break the wire.
It is easy to splice the THHN back together.

Subject: [TowerTalk] Mechanical weak link in leg of dipole

Hello all,
The south end of my 80-meter dipole runs among trees. The trees are higher
than the antenna wire and have limbs which are above the dipole. Big limbs.
The dipole is made of #14AWG THHN. It is supported at its southern end with
about 40ft of 3/16in rope tied off in a tree.
One of the trees that is near the antenna is a large beech. One of its limbs
broke off a few months ago and narrowly missed the antenna wire. I'm
thinking about installing a mechanical weak link in this leg of the dipole
that would break if one of the heavy limbs falls across the antenna wire.
Good idea? Bad idea?
What material would be a good choice for the weak link?
Thanks.
Steve, K8JQ
