I've owned satellite receivers since the 10 ft C-Band dish and before Dishnet or Direct. The laws may have changed but I think the problem is you made the mistake of allowing Cable to be contracted to your home. It used to be and still may be a law or contracted loophole for cable companies {either local or federal or a contract no competition clause a local government signed} that you could not have satellite TV service if cable was active in your home in the past 60 or 90 days. I say this because when I'd switched satellite companies the first thing asked was have you had cable TV in the past 90 days I think it was.
Post 54 ping. Did you ever hear of the rule I mentioned?
