Yagi Tape Measure Antenna

thingiverse

These parts are designed to work seamlessly with 1-inch PVC pipes and 1-inch Harbor Freight tape measure steel. Simply use electrical tape to secure the element holders to the side of the pipe, and then employ the driven element bridge to provide added structural integrity across the driven dipole element. I have achieved excellent results using this setup with up to five elements on the 2-meter band. When not in use, simply pinch the elements to detach them from the holders and store them safely inside the tube. For ultimate portability, consider adding end caps to the design. These parts can be used in conjunction with a wide range of tapemeasure YAGI design guides available online. I was unable to achieve optimal results with the 440 MHz side of the depicted antenna, possibly due to the width of the tape measure material being too great for that frequency. Update - July 4th, 2019: At user request, I added a half-inch tape measure version for use. The 1/2 inch still fits within a 1-inch PVC pipe and is likely best suited for frequencies above 440 MHz. A scaled and curvature-adjusted 1/2 inch driven element STL has also been included.
