Ultraportable Yagi-Uda antenna for VHF/UHF

The idea behind this project is to provide a basket of parts out of which anyone can assemble his or her customized Yagi-Uda antenna for VHF/UHF. For my initial 2m - antenna an additional goal was to come up with an ultraportable design. Both was achieved and if you want to create your own one, this is what you will need in addition to the 3D-printed parts:

Bill of materials:
Aluminum square tube, outer dimension 20 mm of appropriate length
Aluminum tube, outer diam. 6 mm, wall thickness 1m
