The Extended Ku band is not licenced as "satellite only" in the US or Mexico. In Canada, this band will be "Satellite Only" until 2028. When G1 comes to the end of it's life, it will be replaced by a satellite operating in the Reverse DBS band with full NA beams.
Shaw is going to use G1 for mainly Canadian HD locals. Any signal that Shaw Broadcast Services can make a $ on by retransmitting will be on F1R/F2. There will be little in the way of original programming lost to southern subs unable to receive G1.
