[TowerTalk] using trees to anchor end(s) of wire antennas

[Jerry Keller]

Tim... over here, we mostly call them "lag bolts" or "lag screws".  An
arborist friend told me use of lag bolts is, as you point out, much kinder
to the tree. The tree heals right around them with no lasting damage,
whereas anything wrapped tightly around the trunk ("girdling") will
eventually kill the tree.

What's your opinion of using the base of deep-rooted trees as guy anchors?
