Explanation: VHF maritime mobile communication relies on vertical polarization for optimal interoperability between ship stations and shore stations. Both vessels and coast stations typically use vertically oriented whip or collinear antennas. Matching polarization minimizes signal loss, ensuring maximum signal transfer and reliable communication across the maritime VHF channels (e.g., 156-162 MHz). Option B is incorrect because while the transceiver itself must be type-accepted, the antenna array generally does not require separate FCC type acceptance. Option C is incorrect as horizontal polarization would cause significant signal loss due to polarization mismatch with the predominantly vertical antennas used in the maritime service. Option D is incorrect; standard VHF marine radios are limited to 25 watts on high power, so an antenna capable of handling "in excess of 100 watts" is not a regulatory requirement for this service.
