HDTV Antenna (OTA DTV)

prusaprinters

<p>I designed these mounts to zip tie to a standard 1" diameter PVC pipe or wooden dowel (a piece of old rake handle in my case). This DIY DTV antenna works better than the store bought flat flexible square antenna I was using in my attic before.</p><p>This antenna design is based on this article:<br/><a href="https://www.hamradio.me/antennas/superbowl-dtv-antenna.html">https://www.hamradio.me/antennas/superbowl-dtv-antenna.html</a></p><p>Additional stuff needed:<br/>• 14 AWG - 10 Feet - Solid Copper Grounding Wire<br/>• 75 Ohm to 300 Ohm UHF/VHF/FM Matching Transformer Converter Adapter with F-Type Female Coax Coaxial Connector Plug Jack for Cable Wire Antenna TV<br/>• 3-ft x (approx) 2-ft Steel Welded Wire Garden Hardware Cloth Rolled Fencing<br/>• Soldering iron and Solder to connect adapter wires to antenna wire<br/>• RG6 Coax extension cable<br/>• Coax cable connector/adapter to join two male coax cable connectors together<br/>• Lots of zip ties</p><h3>Print Settings</h3><p><strong>Printer Brand: </strong>Prusa</p><p><strong>Printer: </strong>i3 MK2S</p><p><strong>Rafts: </strong>No</p><p><strong>Supports: </strong>No</p><p><strong>Resolution: </strong>.2 mm</p><p><strong>Infill: </strong>30%</p><p><strong>Filament:</strong><br/>[Overture PETG ](http://www.amazon.com/s?url=search-alias&amp;field-keywords=Overture+PETG&amp;tag=thingiverse09-20) Space Gray Post-Printing</p><p><strong>Assembly Notes</strong></p><p>I cut off the metal ends of the flat cable on the adapter and stripped the wire back and fed the wires through one of the 3d printed wire mounting parts, and wrapped them tightly to the middle of each of the two shaped antenna wires and added solder to keep them attached.</p><h3>How I Designed This</h3><p><strong>About the design process...</strong></p><p>I run Ubuntu Linux on all my home computers. This limits my choices for CAD software so I have taught myself how to use FreeCAD since there is a native Linux version that seems to be getting more stable as time goes by.</p><p> </p><p>Category: 3D Printing</p>
