The Dish tech made it out for the rescheduled install this afternoon. He arrived one hour into the 12-5 PM window, and had called just after 12 to let us know he would be here in an hour, which I really appreciated.
He was very efficient and courteous, worked at a very steady pace, and had the 1000.4 installed and tested in just a couple of hours. He included struts for the roof mount, which should help.
I had run the coax and ground within the house and through the exterior walls prior to his arrival, and removed the old dishes while he was installing the new one, which helped to get the job done quickly. He warned me that the 1000.4 signal strengths would be lower than what I measured before, which turned out to be quite true. He commented that the larger dish size helps to prevent rain fade, even though the nomimal strengths are lower. We'll see how rain fade is affected, but for now, everything is working well on both 722's.
The only discouraging moment was when he presented with an agreement to extend the contract for 24 months, for the "upgrade". That topic had not be mentioned to me up to that moment - not on the phone call to Dish, not during the first techs visit on Wednesday, and not before all of the work had been completed today. I told him that, and that I don't agree that this change represents an "upgrade" in any way, since Dish has changed their configuration, and I am just just trying to be able to see the channels that are in the packages I am already paying for.
We agreed that I would decline to sign the contract extension. We'll see what comes from that. If it ends up with attempts at added charges by Dish or any other surprises, I think I am at the point where I would just cancel and move on.
