I finally got a line of sight on the ground for the Superdish. After 3rd attempt at making appointments through Dish, the installer went back saying we need a pole and has rescheduled installation next week. However, I want the Superdish to only point at 121 and as suggested by other forum members, I would like to connect the 4 satellites through 2 SW 21s. The installer is refusing to point to only 121. He says, he is required to pulldown the existing 301 and 500 dishes and take them back. These 2 dishes are just working fine. My only concern is, as there are more leaves in the way of Superdish, chances of losing signals will increase. Does anyone know if we can keep the 301 and 500?
