This is a simple approach to make an easy to assemble/disassemble Yagi Antenna; it was designed to be used as portable antenna for SOTA operation but you can use this design to make a 9 element beam, just print more of the reflector piece. It was designed to hold 3mm welder aluminum rods as elements. The feedpoint is just by pressure on the conductors, no screws needed, just push enough to make a good contact with coax conductors. Also it can be used to satellite operation, printing more reflector piece. The boom is a standard electrical tube of 22mm made by "Tubelectric" but you can use PVC pipe also. The boom also is used to hold the elements when the antenna is not assembled. UPDATED! There is a new feedpoint design which is better, improve electrical contact between the rod and coax cable, and is easy to assemble. Print this piece vertically; this way you will have a clean bed to the small levers.
