Yet Another Center Insulator
thingiverse
This is a center insulator for a ham radio dipole wire antenna. Use a chassis mount SO-239 connector and solder your favorite wire. This requires eight screws that are #4 sheet metal screws, 1/2" long. 5/8" long also work. 3/4" will stick out a little bit. https://www.dxengineering.com/parts/dxe-so239d-1 I really like the high viz copper coated steel wire from DXE, but just about any wire should work fine. I routed the dipole antenna wire in hole on the side, then out the hole on the bottom that is nearest the SO-239, wrap it once (or more) around and then push it back in the bottom hole that is away from the SO-239. Then solder to the SO-239. I added a very poor image that demonstrates the routing of the wires.
