MC2 Post 1648 It's Amazing What You Can Do With a Little FOIL



Like 'Foiling the Invaders', in the movie  "SIGNS."



But a More Inventive Project Could Be:






HDTV Antenna of a Different Color



We’ve seen our share of commercially available HDTV antennas that work really poorly.


If you’re in need of free television and don’t want an eyesore of a an antenna try building this foil and cardboard version. Even it if doesn’t work at all you’re only out about ten bucks.

 

The expensive part is the matching transformer which converts screw terminals to a coaxial cable connection so that it may be connected to your HDTV. You’ll need a few nuts and bolts, but we assume you can beg, borrow, or steal the tin foil, cardboard, and blue that round out the parts list. Glue, measure, cut, fold, fasten, finished! You’ll be watching horrible summer TV in no time!








===================================
If it doesn’t perform as expected just reuse that connector and try your luck with 

a  Fractal Antenna. 
 (the fractal antenna was the key part that made cell-phones possible...Wingman.)

Pictures from weather satellites with a USB TV tuner



Several times a day, a NOAA weather satellite passes over your head, beaming down pictures of weather systems and cloud formations. These transmissions aren’t encrypted, and given the requisite hardware it’s possible for you to download these images from space as [Lovro] shows us in a tutorial video.
