Get a multi-satellite dish to simultaneously view channels broadcast from different satellites on different TV sets. Typical dome dishes only allow channels
from one satellite at one time.
Get a Hi-Definition TV (HDTV) dish (not shown, see for discussion) to enjoy a much higher quality viewing experience.
Get a larger dish - 24, 27" or even 32 (32" dish not shown, see for discussion) - to allow superior pictures in fringe reception areas,
where the signal may be weaker. For example parts of Alaska, the Caribbean, Mexico, South America, Australia, and parts of the Mediterranean may have weaker signals.
