You may recall on on transition day, Memphis had a HUGE thunderstorm come through. My cable was down for a week, or so.
As has been pointed out, the UHFs are fairly easy to get. 5 is another matter. But, having to get it OTA, I fashioned a full-wave loop out of #12 wire, a plastic rod and a couple of push pins -- a 10-minute operation. It worked GREAT, even on the ground floor in Germantown.
Channel 5 on my cable tends to freeze quite a bit, so that antenna STILL gets used and works flawlessly. Still, one wonders why they haven't attempted to, at least, construct a "fill-in translator," as WTVF/Nashville has done.
