 in November 2003 as a means to provide more channels for subscribing customers. Its elliptical reflector is 36" x 20" - more than 50% larger than the round 20" Dish 500. The SuperDish receives signals from three orbiting satellites, as opposed to two signals with a DISH 500. The three satellites are at 110°W, 119°W, and either 105°W or 121°W depending on customer requirements. The 105-degree orbital slot provides local channels via Ku band
