For some time we have been working on new Antenna Launcher Kit instructions. We have “started over” with a new Order of Assembly that is designed to better align the launcher with the new barrel to chamber Spacer Block. It has new text and lots of new photos. It also contains instructions for Leak checking and repair, and for assembling Launch Balls. Find it on the Info page, look for the 2019 Kit Instructions. The old instructions are still there marked 2010. If you have already started assembling you should stick with the instructions you started with, however you can look at the photos to get more clarity as to how the parts go together, but understand that the order of assembly has changed and starting with one set of instructions and jumping to the other can lead to trouble unless you have not yet glued the barrel endcap to the “U” structure.
