Vídeo: My Cubical Quad Antenna Project, 144MHz, Part 2 - Canal HamRadioConcepts
The 7 element VHF cubical quad project is coming along very nicely. I have 3 elements so far completed. I 3D printed the hubs on the boom, and end caps for the spreaders. I'll post these files and links soon, so you can build one if you want. Should be under $100.
