Antennas and trees K6hmp on 4/10/19
I have 80 ft pine trees with a 140ft 14ga wire dipole @ 70ft+
I use a home made PVC pneumatic launcher with various weights of "slugs" or "carriers". Utilizing a large open face reel with 6-8lb test. My technique is to shoot over the crown and stop the payout of line. This way the slug falls close to the trunk of tree. Varying the PSI controls the velocity and range.

Either way, be cautious around the obvious. If weight is too heavy and the shuttle stop suddenly; it will sever from line. Then it becomes a dangerous and uncontrolled projectile.
