I use a slingshot with a 2-ounce lead egg sinker and 15-pound test monofilament line. I've been able to get lines up 100 feet in my pine trees using this method. After I shoot over the tree, I tie some heavier nylon trotline to the monofilament and draw it back slowly over. I may use the nylon line as a support or, or I may pull some dacron rope back over with the nylon line. I've used this approach for quite a while, and it works. 73, John N5CM |

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. |
