Yeah I have two dish installs at two different houses, one's a 500, one's a 1000.2. The 500 is just barely visible from the street, almost completely hidden though. The 1000.2 is not visible at all from the street. It's way up high on the house and on an incline on the house where it's not visible at all unless you go beside the house and look way up where you'll only see the backside of the dish.
In the house with the 500 I had them run the line around the parameter of the house, hidden by siding, and drill a hole near where the other TV was. With the 1000.2 that house has a basement so they just ran it all down there, granted it was a little sloppy, but I tidied up behind them tying them up on the floor joists as opposed to them just hanging in your face while you're walking around down there. Wasn't a big deal though.
