And I'd be willing to bet, that they are also too cheap, and either install antennas in their attics, still trying to use old-fashioned rabbit ear antennas, or those stick-on antennas as seen in Walmart. None of that has anything to do with the reliability of DTV signals, but more that certain viewers can't be bothered to do what it takes to receive free OTA TV.
I've been in the TV business for a long time and went through the DTV transition in 2009. You couldn't be more wrong. It absolutely does matter what "some people do". It's not the DTV station's responsibility when a handful of extraordinarily frugal, or lazy viewers can't be bothered to research, then install proper reception equipment.
David and I walked you through what is needed to install an antenna on your home. I even linked models, vendors, and pricing. I even included a list of installers located in your city. Instead, all you do is whine and blame others because you personally can't be bothered to do a proper installation. Again, none of this is the TV station's responsibility.
