Description
This is a jig you can wrap the wire around to create the “cloverleaf” circular polarized antenna lobes.
In the source code you can change the frequency you want to create the antenna for and the wire thickness.
Note – there are two designs for it – one of them “open” where you wrap the wire around the jig, the other “closed” where the wire starts in a hole, more like the wooden dowels (but it may take some bending to remove it from the jig afterwards).

Printing Instructions
Printed a test unit using ABS at 40% infill and looks sturdy enough. I’ll update the status after a few weeks of using it.
