Pie-tenna, the Simplest HDTV Antenna Possible, Possibly.





Introduction: Pie-tenna, the Simplest HDTV Antenna Possible, Possibly.

Redneck Contest

Redneck Contest

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.

I watched the video but don't understand what you do with the thumbtacks and where the pie-tenna actually goes. Where do you put it so that you get reception? And are there any impediments to reception, such as concrete basement walls?

Wow, that was easy. Mocked this up in under 5 minutes, with just tin foil and cardboard. I live in a fringe area, but managed 8 channels. Doubtful a indoor antenna bought would do better.

i'm so mad i did what you did in the vid and it didn't get any stations at all, it appears that everybody's else's works... so frustrated

i did use tin foil but otherwise nothing please answer ASAP

I was out in the country with no antenna and no pie plate, so I tried this with a loop of 4 conductor speaker wire about 9" in diameter. Both hot and ground were connected to different wires in the same end of the loop. I got 40 channels.

Did not work for me! Followed instructions to a T, even made some adjustments when it wouldn't work, still didn't work. Super pissed. :/

Awesome! I just made one out of aluminum foil and it picked up most the stations around my home just as the one I ordered on line. I used a splitter and some wire to connect to the foil. Taped the foil to some cardboard and hot glued the splitter to the cardboard then connected. Works great! Thanks!

Did you mod a coax cable to have only one connector (strip the wire casing on one end)? Or did you buy it with only one connector? (I've been having trouble finding one like that)

Made this with cardboard and tinfoil. Connected coax to antenna with paper clips. As you can see, this is a total hack-job but it works beautifully. Didn't even mount it, just rested it on the edge of my bookshelf. Picture attached of setup and me watching the green Bay game.
