I think the push will come from broadcasters. They will co-locate and share frequencies and delivery less than they deliver today. They crank up that ATSC 3 tower at a mighty 1 W and wait out the five years. Two or three years in, they can crank up the power and start demos of what it can do. I think the TV manufacturers will be on board before then. And policies can change. ATSC 1 and 3 co-existence, and no mandates.
