2.4 GHz Biquad Yagi Wifi Antenna

No real changes over ReallyBigTeeth's upload. I created a closed end tube with thicker walls because CURA won't render code for structures that are too close to your printer's extrusion width, so I made the tube 2mm thick. My major contribution is a snap-on clamp to hold the antenna securely in place. You will need to add a nut-bolt-washer combination to complete it effectively. As a test, I was able to achieve 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 enable 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 precisely. This was an aesthetic decision, and may not be optimal in performance. Also, make sure you rotate these models and lay them flat when printing. Fusion 360 likes to flip the X and Z axes on save for some reason on my setup, so you'll need to correct it manually.
