3D Printed TV Fractal Antenna with Wall Mount

thingiverse

A surprisingly effective DIY 3D printable dipole TV antenna built from simple materials including plain wire, one end of a coax cable, and some basic machine screws. It may not be perfect, but I've managed to receive three channels from one repeater station and four from another repeater in my rural area, all thanks to its surprisingly strong digital signal reception capabilities. My area only features the new digital TV channels, and I'm eager to hear any suggestions for improvements or upgrades - maybe even implementing them myself! The antenna's unique fractal pattern was inspired by William Rucker's instructable on making a fractal antenna for HDTV and DTV plus http://www.instructables.com/id/How-to-make-a-fractal-antenna-for-HDTV-DTV-plus-/?ALLSTEPS. To achieve this design, I relied heavily on the 4:1 coax balun calculator provided by n-lemma.com/calcs/dipole/balun.htm to ensure accurate center frequency matching - with an estimated 554 MHz, which I've yet to verify personally.
