I ran across this oddity from thirty years ago while scanning things for work yesterday, and thought it might be entertaining in light of the recent DTV switch. In 1979, the Triad got its first commercial UHF station (there had been a PBS station on channel 26 for some time, but apparently no one cared) and they placed ads showing the uninformed masses how to get the signal. Sound familiar?
I love strange old technologies like these, especially when they’re suddenly back in demand. Those UHF loop antennae are hot items again, since most TV stations in the digital era are broadcasting in the UHF band, even though their “virtual” channel numbers have not changed.
