$4 Yagi

This is my interpretation on the Dual Band Yagi (7x 70cm elements, 4x 2m elements) originally designed by KG0ZZ that is primarily built from steel clothes hangers and a wooden 1x2 stake. I wanted the ability to make fine adjustments without major rework- so I made the following changes:

1. Used a garden stake sourced from Fred Meyers that measures 3/4x3/4x42 inches (not 1x2)
2. Sourced hangers that had insulated steel wire that had an outer diameter of 1/8 inch from Fred Meyers
3. Designed 3D printed wire holders that can be slid up and down the stake, and secured into the stake with M2 screws. This allows for spacing fined tuning. The antenna elements are clamped in place with M2 screws, trapping them in the grooves. This allows for element in/out fine tuning by loosening the screws. The driven elements are trapped by M3 bolts (you must drill out the existing 3D printed holes in those locations with a hand drill, I recommend just under 3mm so that the bolt creates its own threads whe
