Fw: Elecraft Antennas in trees

[Jim AB3CV]

i watched an arborist doing some work next door and he showed me the "old
man's toss". it is a between-the-legs toss and it really works well for me
compared to the "lariat toss."

it uses the arms, legs and back and is directly in line with your spine.

i went home and with very little practice i can now hit 50+ feet with no
problem. this lets me launch a messenger line to take up my line saw with
which i keep the trees near my dipole trimmed.

FWIW I'd like to relate what I saw at the recent Field Day.

The antenna crew used an air gun, similar, I think, to the ones used with tennis balls, but the projectile was a small cylinder about 1" in diameter and length, probably metal. The air reservoir was charged using a pump designed to inflate tires. A valve seemingly designed for lawn sprinkler systems was used with an electrical circuit to release the air charge into the pvc pipe barrel. The shooter did not aim for a specific branch but at a very steep angle over the top of the tree. This system had no problem getting the projectile way above the tops of tall pine trees. Due to the steep shooting angle, the projectile with fishing line also came down steeply on the other side (good idea if there is a building that you don't want to hit!). At this point the line was on top of several branches, big and small. The shooter would slowly pull the line back, directed by a second person with the projectile in view. This way several small branches were cleared without snagging the projectile. When the projectile was hanging down from a sturdy branch, the line was released to get it down to the ground.
