Do they even care at this point? And wouldn't it just be easier to build a new tower? That's only semi-sarcastic. Since the conversion to DTV I have lost count of the number of off-air incidents that have happened with the two local towers. But this one is certainly on record as being the longest.
Why is this equipment so much more prone to failure than the former analog transmission equipment?
Rick, with all due respect, did you even read the other pages of this thread before posting? WGBH is NOT off the air, they are at reduced power for the time being. So if you live outside the coverage area , you won't see the signal.
And of course they care. They have been working on the issues with the transmission system since it failed. Why do you people assume that this is being passed off? I strongly suggest you go back and read Mr. Yankowitz's post about it. It will explain a lot to you.
As far as the failure rate, from what I know, this is the only large outage they have had since running at high power. The combined DTV room definitely has more going for it, because of the power level being used. With analog TV, the power levels were in the low 50kW range. With DTV, the power levels are closer to 500kW. With 10x the power level there is a greater risk of RF conditions like a "burn out" or other catastrophic failure, but the risk is small, and what happened with the antenna systems here, is unusual.
If you're seeing a constant "outage" rate, there may be a issue with your reception/receiver. Remember with DTV, there is no "weak fuzzy signal". Due to the Cliff Affect, your signal is there or it isn't. If you happen to be on the edge of the WGBH signal, which is lower than WBZ or WCVB, during normal conditions, you can have environmental conditions cause the signal to drop out,
