No real changes over ReallyBigTeeth's upload. I made the closed end tube with thicker walls because CURA won't render code for structures that are too close to your printers extrusion width, so I made the tube 2mm thick. My big contribution is a snap-on clamp to hold the antenna. You will need to add a nut-bolt-washer combination. Go nuts with this. As a test, I was able to get 100m with -67 dbi on my wifi range with this antenna in a very noisy environment. The plan is to connect a satellite building to the main structure on a farm to allow remote sensing and control systems to be online. The reflector is just a single-sided copper clad PCB board cut to match the general shape of the elements. This was an aesthetic decision, and may not be optimal. Also, make sure you rotate these and lay them flat when you're printing. Fusion 360 likes to flip the X and Z axes on save on my setup for some no good reason.
