This weekend I'm going to attempt to build my own DTV/UHF antenna to be mounted in my attic, hopefully in time to watch the big game, over the air, on Sunday.
Ernie turned me on to these instructions from Make.
Update: The antenna worked! Here are the results.
I've been using just a pair of rabbit-ears the last few weeks which actually work well with the digital TV signals. No adjustments needed between channels, although I am probably only 20 miles away from the majority of the towers in town.
Once the antenna is done we'll see if we can't pick up a little signal from some place further like Bowling Green.
