You pretty much lost me with the new technology. I do not know how that works in rural areas.
My business was radio electronics, but as a side line I sold the old 12 foot dishes that picked up C band sat transmissions. OK, that was 30+ years ago. I am now happy with my G-sat Ku band system.
Quick answers to: "Does the US still have old broadcast TVs?"
Yes. But ones made before 1999 or so will need an inexpensive converter box, since the picture format has changed from analog to digital.
(Hopefully that's a lot clearer.)
