I have updated the Antenna Launcher Instructions with a new version that has many improvements, updates and a few corrections. In particular the assembly procedure for 3D Printed Endcaps has been added which will start shipping in kits soon. These have been shipped on the pre-assembled launchers for some time. They offer easier assembly and better service since the barrel can be removed without removing threaded components from the main pressure chamber.
See the Info tab above for the Launcher Assembly Instructions. Older versions are also available for those who are in the midst of assembly (generally it is not good to change instructions in midstream), or who wish to refer to or use older instructions.
