provided on the SCT if the transmitter has a power excess of one watt, this will allow the operator to reduce the power to less than one watt, resulting in a reduced battery power loss. Along with other requirements the IMO has made it mandatory that the antenna be vertically polarized, allowing all radio antennas to be within the same plane, this ensures that the energy transfer from each radio is high. The IMO requires that cargo ships between 300 and 500 gross tons must carry two SCTs. Passenger ships carrying more than 12 passengers on international voyages, and cargo ships of 500 tons or more must carry three SCTs.
