Mast Top Insulator

This is an antenna insulator with SO-238 connector to allow feeding directly with coax cable. It is sized to fit over a 40mm mast, such as fiberglass military surplus mast sections.

The four holes on top and two on each side allow use will dipole or NVIS antennas.

I printed with supports so the right angles stayed right angles.

I also thickened the walls and used high infill for strength.
