Driven Element Box for VHF/UHF Antenna

thingiverse

The concept behind this was to create a simple, easy-to-assemble driven element for a 6m to 70cms Yagi, which could also incorporate a choke into the box. Although it might be somewhat large for a small 70cms beam, this design proved to be neat nonetheless. This project primarily focused on creating a 7-element 6m portable contest antenna for the UKAC, and I aimed to have it ready as quickly as possible on-site. The passive elements will clip onto 10mm pipe clips attached to the supports, similar to my 2m one featured on my blog at www.chopcat.co.uk. This is plan B of the prototype shown in the photos. Initially, I made separate elements and then reduced the box to three parts, eliminating the need for two brackets to clamp onto the boom. Following a short time trying to figure out how to create my new R2 print after its touch screen stopped working, plan B was printed (in orange). This is the composite version of the box designed for a 30mm square boom. I will update this project as I continue printing and fine-tune it with field tests. Designed in SketchUp and printed on an R2 using PLA so far.
