Customizable Yagi Element Clip

Simple clip I made for my 2m & 70cm band yagi antennas.

The uploaded STLs are made for a 45mm wide bar. If you want to customize them for your measurements use the OpenSCAD file and the built in customizer. I do not recommend making clips for bars less than 30mm wide with these files.

If you are looking for Yagi measurements, use the very resourceful website of DK7ZB:

What you need:

For the Yagi:
- Bar to mount the clips on. attached files are for 45mm wide bars
- Coax with connector of your choice

For each clip:
2x 3,5x16mm Wood Screws

For the dipole clip:
2x M3 Screws (length: at least 4mm longer than diameter of element
2x M3 Nut
2x cable shoes

Construction:
It is easier to align the edges of the clips than the center of the elements. If you need to flip an element due to the proximity of another clip (see second picture), just subtract/add 27mm.

Mark the center of your elements with a pencil. The marks in the clips help you with centering. I use superglue to keep the elements in place. The best way to do this is to slid the elements a bit off center, drop the super glue on the edge of the elements. Then realign the element while turning it. This ensures that the glue is smeared on a larger surface.

The dipole elements can be a bit tricky. If you do not drill straight down, you'll end up with tilted nuts that won't fit properly into the space below. File the surfaces of the dipole elements a bit so that you get a better contact.
