Update: Extensive testing has been performed by Intelsat and the earlier problems with co-satellite interference have been minimized.
If you are continuing to experience reduced quality it could be related to the beam width and/or misalignment of your dish. Smaller dishes with beamwidths greater than 2 degrees and reduce off-axis attenuation will continue to experience interference. Dish aiming of dishes with wider beamwidths is extremely critical to minimize the interference between the neighboring birds.
