Television antennas are made of a series of metal rods cut to exact lengths and positioned so they receive a particular television frequency. The following design was invented in the 1960s by an engineer named Doyt Hoverman. It is particularly sensitive in the UHF frequency range, the same range used for the majority of digital television transmissions.
This coat hanger antenna isn’t a project of my making, I merely wanted to comment on it in this space. All credit goes to Make:television for posting the (attached) instruction PDF.
Begin construction of the antenna by marking a 3” x 20” board as shown. Note that these dimensions are important to get a good signal with the finished antenna.
This diagram was modified from the version in the PDF.
Attach the matching transformer to the center two connections of the antenna.
Conclusion
I put this project here because I completed it and wanted to add my comments. I omitted the base which I didn't build, and updated the schematic. Please move or modify it as necessary for content and copyright compliance!
