🎯 Quick Demo: How to Use the DX-Launcher Using the DX-Launcher is incredibly simple — and effective! We got the perfect line-up on the first shot for the inverted L antenna we installed at KO8SCA. Here’s how we did it: We used Manstrant rope as the pull line — strong and reliable. When threading it through the tree, we taped the pull line securely using electrical tape to prevent snags and tangles. A single, smooth launch — and the line was perfectly placed. That’s it! Fast, clean, and spot-on.
