Yep. If the equipment is leased or purchased from Dish, they definitely want to install the setup, since they have to support the setup. I don't doubt most folks here are savvy enough to do it, but the average customer? Nope. Think of it this way...think of the average customer, and then remember that half of them are below that average.
As a Dish employee, my opinions are my own, and do not represent my employer in any way, shape, or form.
