[TowerTalk] Tree's and Screws

[john at kk9a.com]

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  ;)
