ABSTRACT:
An antenna stabilizing apparatus for use on a marine vessel comprises a base body, a housing, a carrier, and a limiting member. The housing is mounted on a top of the base body and internally defines a receiving space. The carrier has at least one antenna carried thereon, and is connected to the house via a hanging member to suspend in the receiving space. The limiting member interconnects the carrier and a bottom of the housing to each other and limits a displacement range allowable for the carrier. With these arrangements, the antenna stabilizing apparatus is able to minimize the adverse influence of the rolling and pitching marine vessel on the signal receiving and transmitting via the antenna mounted on the marine vessel. Therefore, the marine vessel can navigate the sea more safely and stable wireless signal transmission via the antenna mounted on the marine vessel can be ensured.
