All the local channels themselves has to be on the same satellite dish, that does not pertain to the other channels. They could have all the locals on one seperate dish and then all the core channels on another and that would be legal. The reason why they have to have all the locals themselves on the same dish is due to the fact that they put some at one orbital location and some at another requiring two seperate dishes. Those channels that had to have the other dish were what many would call the ''less preferred'' or ''less popular'' channels that most may not watch. They knew that most wouldnt want the other dish or didnt know about it so they got away with that. The FCC decided that it wasn't fair to those ''less preferred'' stations that they should be offered to anyone that could get the most popular locals so the one dish requirement commenced.
