The file '1.5 GHz Helix Scaffold Set (Inmarsat, Iridium, Cospas-Sarsat, …) 3D Printer Model' is (stl) file type, size is 284.4KB.

Summary

I have released an OpenSCAD file on github that can generate any helix scaffold proceduraly, check it out: https://github.com/sgcderek/dsgc-helix-scaffold

A set of 3D-printable scaffolds for 1542 MHz. Supports wire with up to 4.5mm diameter.

Make sure to download a suitable stl to your application;
NH1542L1 - 1542 MHz, left-hand circular polarization (offset dish feed)
NH1542L2 - same as above, includes extra leg support
NH1542R1 - 1542 MHz, right-hand circular polarization (direct reception from satellite without a dish)
NH1542R2 - same as above, includes extra leg support

Can (and should) be printed with no supports and a big layer height.

Before winding, it is important to pre-form solid-core wire into a rough helix shape. If you wind solid-core wire directly into the scaffold there's a good chance that one of the legs will break.

The holes on the mounting legs are 1cm in diameter, a washer can be used to mount it with smaller screws.

If you want a modified version, let me know and I'll be happy to make it!
