Parts for 3D printed Yagi–Uda

Required Parts:

• 16mm PVC pipe
• 2.5mm metal rod
• 2x M6 nut and bolt
• Coax

Printed Parts:

• Parasitic Holder - mount for the parasitic/passive elements
• Radiator Holder - mount for the driven elements
• Parasitic Holder screws rubber - mount for the parasitic/passive elements where the metal rod is placed from the top and secured using screws or a rubber band. Useful for an antenna with bent elements.
• Boom Split - Optional connector for splitting the PVC pipe

Build Guide:

Important: The metal rods are friction fit to the Parasitic Holder, the rod's diameter needs to match the Parasitic holder hole diameter, plus some tolerance. 

The provided files work for rods with 2.5mm outer diameter, if you have different rods you need to edit the provided step files. 

Tip: If your rods are slightly loose in the holder, you can add a drop of CA glue to them, to make them thicker in the place they touch the holder.

• Find antenna dimensions:
  • use a Yagi Calculator 
  • or just use some plans from the internet ( for example, 2m 70cm Moxon Yagi)
• Cut the metal rods to length
• Bend hooks onto the ends of the driven elements (look at the pictures, they should fit around the M6 Bolt)
• Assemble the Radiator Holder:
  • strip a few cm of the end of the coax
  • place the wires into the hex-shaped holes
  • push the nuts into the holes, they should press against the wires
  • secure the nuts with CA glue
• Put all holders onto the PVC pipe, and secure them with CA glue
• Secure the driven elements using the M6 nut

For storage/transport, untighten the M6 bolts and fold the driven elements and pull the parasitic elements out of their holders and put them inside the pipe
