Support and stand-off parallel elements in a magnetic loop antenna. (Or maybe you'll find some other use for this.) Secure the standoff to the elements with zip ties, maybe wrap elements with silicone tape first to prevent slippage.

Default is sized for adding a parallel loop of 5/8" aluminum tubing to an MFJ-1786. Spacing may not be quite right yet. (Something I intend to experiment with in the near future, one and then two parallel loops.) I expect to use four of these per parallel conductor.

OpenSCAD source included.
