Another crazy ota tv antenna
The wiring sort of. One connect wire for each side.

Antenna redo.
Made an antenna guessing at the specs. Also did it do see how critical the angle of the dipoles were. Antenna pattern: http://web.archive.org/web/20130610164242/http://tradewhen.com/Log-Periodic-Pattern.pdf Original version: The antenna did not work that well. So I went back and looked at the original picture and noticed the angle was quite different. Oops, the original angle used was a bit wide. Hmm. S/B: Now, the new version with the corrected angle. Now to test it. Tested average.... Other antennas to look at: http://www.instructables.com/id/Antennas-TV-Wifi-and-etc/ A bit about antennas:
Yet another TV antenna.
Playing with OTA tv antennas again.. Took an aluminium plate and cut it to roughly the dimensions of the $49 commercial antenna. If I had not been in a hurry, the antenna would have looked nicer. Without resetting the channels on the receiver still was able to access over 80 tv stations. Not bad for a $3 investment. Update: Another antenna comparison. No CBS affiliate either. Amazon wanted $99. Again only a $3 investment for me. Parabolic antenna and a yagi antenna.

Making of a sprial antenna
Experimenting with gifs to see if they do a job as well as a movie. More antennas at: http://www.instructables.com/id/Antennas-TV-Wifi-and-etc/
Yet another OTA HDTV antenna.
Revision3 was touting this one antenna that sells for thirty five dollars. Seems like a pretty uncomplicated design. Went to the site to see if they had the specifications. In some ways it was like antennas I have already made, That antenna tech has prior art so to speak for sure. Looking at the picture, I thought I could create something like it fairly easily. In about an hour a recreation was made. Anything but professional looking. Worked well, but not as good as what I have already made. It would not get the station with "The Big Bang Theory". So that was an immediate fail. In any case I have another antenna plan that can be easily implemented if I need to build an antenna on the fly.

Rabbit ears.
Finally testing some over the air foil based antennas Also wanted to test the composite output of an old computer I have made. Next antenna, I think is a gray-Hoverman antenna. I tried to follow the specs the best I could. The last antenna I tested was a fractal based antenna. it was definitely directional.
Ehow DTV antenna revisited.
We decided to do an indoor version of the Ehow outdoor DTV antenna. For more details see: http://www.instructables.com/id/Ehow-outdoor-and-indoor-DTV-antennas/
Super antenna cheap.
One of my side hobbies is to make foil based equivalents of traditional antennas. This is my latest prototype of the Gray-Hoverman antenna. Just $5 dollars in materials. It is also almost light as a feather. My next goal is to step it up a bit with commercial antenna clone. Probably do this one with coat hangers. Looking for the specs.
