Modular 2m Yagi for portable use
Building a portable Yagi Uda antenna was actually THE reason why I got my 3d printer. My first project was a fail. Since I wanted an antenna design that uses elements that can be split in half for easier packing and carrying around.
My first try was with aluminum rods and drilled holes. I cut a thread in them and used a threaded rod to connect the elements. It did not work out as I dont have a drillpress and can’t cut threads 100% perpendicular by hand. So the project laid around until recently.
