FWIW, I've had rubber core bungees from Lowes survive several upstate New

There are far better ways to allow for trees swaying in the wind. A
pulley and suitable weight, combined with a suitable rope, can withstand
a lot of stress, but can be relatively inexpensive. I use the 5/16-in
rope sold by DX Engineering and several other ham vendors.

I use pulleys either from a store that caters to sailboat owners, or a
special type with sideplates that rotate that a rope can be laid onto it
rather than having to be pulled through from one end. This maks it much
easier to rig.

Weights can be anything from old window sash weights to buckets of
concrete with a hook inserted in the concrete, to water jugs filled with
dry sand (what I use).
When it costs hundreds of dollars or a serious effort to get the antenna
up there, skimping on mickey mouse half solutions that can put it on the
ground and require another climb doesn't make sense.
