• A ship rolls to 10° on moderate seas, either way, sometime more (vessel and sea conditions) • Antenna Gain of 9 dBi => 12° Antenna elevation beam-width => allows for +6° roll and -6° roll
either way.

• Too high gain = overshooting the target base stations on shore• Too low gain = inefficiency
• Antenna gain of 4 to 7 dBi => 20° to 40° elevation beam-width => allows for 10° to 20° roll either way.
