I watched Survivor Thursday with no noticeable reception problems. I think this is the nature of the beast - channel 3 is susceptible to changes in the atmosphere, weather, etc. I'm less than 2 miles away, but my crummy rooftop antenna does not have a clear shot - the building next door blocks it. Some days it pulls it in fine, some days it's not watchable at all. On those days, I pull out the rabbit ears, by flattening them all the way out I get a stable signal in the high 50's which is very watchable. Thursday was one of those days.
It's ridiculous that almost everyone says the same thing - 'all the other digitals come in great, except for WBBM.' I can use an 8" loop for UHF signals, but I need something 8' wide to get ch 3?
