Build your own “Super OTA TV Antenna”
Did you know there are more than twenty five over-the-air (OTA) television stations currently broadcasting High definition (HD) signals in Canada plus many more HD stations which spill over into Canada from the United States?
The knowledge that a multitude of free over-the-air high definition signals was available was the impetus for a bunch of retired and hobbyist antenna engineers working together in the Digital Home forums to create a super TV antenna that can be built by just about anyone.
The Digital Home designers began in 2008 with an obscure 1950s UHF TV antenna called the Hoverman and subjected the design to modern software-based computer modeling in hopes of optimizing its mid-range performance.
After a lot of work, the design team came up with the new Gray-Hoverman antenna which the group claims is more powerful than similar commercially manufactured consumer antennas in every category, sometimes by whopping amounts.
In a act of generosity, seldom seen these days, the group released the design, diagrams, and schematics of the antenna under the GNU General Public License so do-it-yourselfers can build their own Super Antenna.
Quoted one of the testers, a former U.S. Government antenna engineer: ‘Boy, this antenna is hot… This antenna is a vast, and I mean REALLY VAST improvement over anything I have used.’
You can read about the Gray-Hoverman Antenna on the Digital Home website or then join discussion thread of the Gray-Hoverman development which gives the background of their great work.
DIY’ers from the world over are welcome to join the discussion.
