1. US20100245189 - Vehicle-Mounted Antenna Device

a base plate on which a circuit board is placed;

a housing covering the base plate;

an antenna mast base structure, on which the antenna mast is provided, fitted to the housing; and

a water discharge flow path linearly formed in the housing as viewed from the upper portion of the vehicle-mounted antenna device, which extends continuously underneath the antenna mast base structure while being inclined relative to the base plate.

the housing has an antenna mast receiving groove for receiving the antenna mast, the antenna mast being formed so as to be inclined relative to the base plate, and

the water discharge flow path includes a water discharge groove formed in the antenna mast receiving groove.

the antenna mast base structure has a folding structure allowing the antenna mast to be foldable in two directions,

the housing has first and second antenna mast receiving grooves for receiving the antenna mast, the first antenna mast receiving groove extending in one folding direction of the antenna mast while being inclined relative to the base plate, and the second antenna mast receiving groove extending in the other folding direction of the antenna mast while being inclined relative to the base plate, and

the water discharge flow path is constituted by the first antenna mast receiving groove and a water discharge groove formed in the second antenna mast receiving groove.
