If you want to serve those areas with a USEFUL OTA service, then you are far better off deploying translators from the nearest large market. As broadcasters do, at least sometimes. Otherwise, all you will do is drive the folks to DBS. Yes, maybe even on-channel repeaters, in some cases. NO, these would certainly not qualify as SFNs, and that's hardly just semantics, Craig. > You did no such thing. You simply explained where the big > stick transmitters are today.

Give some specifics on this "ring," just so we aren't just wildly waving our arms, Craig. The simple fact is, a viable "ring," as you call it, would consist of maybe two towers spaced closely together. While they might make close-in reception easier MAYBE, they will do absolutely nothing to help the distant reception problem, and may actually make it worse. It all depends how tall these towers are. If they are big sticks, then for distant reception they would approximate one big stick with the same ERP as the sum of the SFN sticks. There was a lot of thoroughly uninformed hype about SFNs a few years ago, Craig. People just latched on to the notion, as if somehow it came for free. As if there were no constraints, no qualifications. I never bought into the hype, and you seem to prefer to argue using the vaguest of descriptions. I gave you real-world examples such as Berlin and Paris, and still you persist.
