[TowerTalk] Tree's and Screws

[Steve Jones]

I wouldn't use a screw.  All my many wires have always been supported on
pulleys.  Shoot a line over a high limb with a bow and arrow, use that to
raise the pulley, and hang a counterweight at the end of the line near the
ground.  When the wind blows the weight rises and falls rather than snapping
the wire.
Protects the tree, the rope, and the wire.
73,

Grant and Larry have very similar callsigns.

Usually I have no problem finding a branch for tying off inverted V's to, or
sometimes I wrap around the trunk of smaller trees.  Eventually the tree
would grow around the rope however my wire antennas are all temporary.

I've put a lot of Zn plated and mostly hot dip galvanized lag bolts into
trees of all varieties over the years and seen no problems except the need
to back them out a bit as the tree grew around them. A good sign I think.
When installed, I leave at least 3/8 to 1/2" slack for growth.

The arborist or mill that might prune or harvest the tree someday would
appreciate their removal when no longer needed.  Instant trashing of a saw
chain.

Absolutely no copper or Cu alloys (bronze, brass) or plating should be used.
Stainless I think is ok, but rarely has been my fastener.

PS: hope you don't contest with your call  ;)
