Summary

Bigger, Beefy, and Better than previous versions!

Jig/Guide/Yoke for creating a 1/4 ground plane antenna suitable for transmitting. Uses brass rod for the elements.

This MkIII design boasts the following features:

Thicker yokes for support-less printing and improved rigidity.
Dedicated cable-tie mounting holes.
Alignment studs for easier assembly and improved rigidity.

My specific instance of this object was designed for the 2m amateur radio band.
