[Elecraft] Line into trees

Well, I think you folks are making it tooo difficult.. 8-)
For years, I have used a light bow (30-40 lb pull) with practice arrows to
shoot lines over the tall Georgia pine trees that I use for antenna
supports. It is simple and effective. I can control the path of the arrow
and the amount of power needed, according to the situation.
I tape a couple of nails to the arrowhead, to add weight and make the tip
blunt. I use 30-lb test monofilament line tied and taped just forward of
the fletch (I think that is what you call the feathers part!). I lay out
the line in a s-pattern, estimating the amount of line required (twice the
height of the tree). I plan my shot, at a high angle. My plan is to just
clear the top of the tree and let the weight of the arrow pull the line
down. Of course, I avoid trajectories that include houses, people, pets,
etc..
After the 30-lb line is across the tree, I attach some 50-lb line and pull
that back across the tree. If my antenna halyard is heavy, I may use
another intermediate size (say 1/8" nylon line) before I attach the halyard
and pull that across the tree. I usually tape the line junctions with duct
tape to help avoid snags. If I do have a snag, I can usually work it out by
pulling the line back, a bit, and then trying it again, with a bit more
force.
I have tried slingshots, fishing rods/reels, tying the line to a wrench and
slinging it across (lost a window trying that one!) and climbing the tree.
The bow/arrow works best for me!
All of the devices, previously described, will work. But, the operator
needs to be comfortable with the selected device. A little practice before
you try the "big" shot is always a good idea.
Have a happy antenna-raising weekend! I am headed to a little swapfest up
around Dalton, GA, to see if I can find some new stuff!
73,
