Centerpiece for a dipole antenna, 5mm coax cable (RG-58) and various rod sizes (4,5,6mm).
There is plenty of space inside for the wiring. The generous size also makes it pretty sturdy and has no problems to support long/heavy poles (2-3 meters per side) in any orientation.
A bit overkill for smaller pole sizes.
Print two of these in a UV/heat-resistant material (PETG or ABS) to complete the assembly. Wire the rods using one side and test your setup. When satisfied, line the interior with silicone and close shut.
Be sure to take an action shot during the first comm-check ;)
