The rings in the above map show the power level in dBW (decibels) transmitted from the satellite. The larger the number, the stronger the signal will be... and the smaller dish size you will need to maintain connectivity.   For the 1.2 meter satellite dish, you will need to be within the 46 dBW ring. For the  .95 meter mobile satellite system, you will need to be within the 48 dBW ring.   All regions within a ring may connect.
