Update : After receiving 8 calls from TW to confirm tomorrows appt, I called them again, sat on hold for a few minutes and then got a human. I explained the situation and asked if he could "Please make the calls stop" When he asked if there was anything else he could do, I told him he could give the tech a heads up that it is a area issue or he should bring a bunch of new boxes. I was told that regardless of my opinion the tech would need to find the problem himself.
Within the hour I received another call explaining that there has been a area wide issue which has been resolved and my appointment had been cancelled....so confused, but it works...for now.
As far as a dish system goes.. I can't. Some folks have trees in the sight line- I have an entire mountain.
