DETAILED DESCRIPTION
FIG. 1 illustrates a prior art antenna system in a vessel. An outdoor omnidirectional antenna 102 is connected to a four-port repeater 104. The four-port repeater 104 is powered via power supply 106 and is connected to one or more line amplifiers 108 which in turn are connected to one or more panel internal antennas 110. The omnidirectional antenna 102 acts as a donor antenna which receive donor signal coverage from base station and tower signals from land. The signals are passed to the repeater 104 which amplifies the signals before they are split between line amplifiers 108. The line amplifiers 108 further amplifier the signals before they are split and passed to panel antenna 110 which are located internally in the vessel.
