Pie-tenna was born out of a desire to make as simple an HDTV antenna as possible.
Retail antennas are too expensive for what they are. And other antenna plans? Who wants to measure, make fractals and really, who keeps baluns on hand anymore? So, after much googling, and patent searches......
The only supplies you'll need are a disposable aluminum pie plate, and a section of coax, with a connector on one end. The only tools, a CD, a pair of scissors, and some thumbtacks.
The video should be self explanatory, if not, ask.
