Design goal: create custom part for assembling Yagi antenne.

You can print light yagi components.
The boom is 25 mm Al pipe but you can use pipes from various materials (this affects only the weight of the structure).
Elements are 8 mm Al tube. Reflector for 2m antenna is divided to 2 parts. Is longer than 1m and is connected with screw terminal.

For example I assembled yagi 8 + 6 elements 2 / 70cm bands
