PURPOSE: To construct a eaves gutter and mount an antenna by mounting a conductor wire constituting an antenna in lug parts at the upper ends of both the sides of the eaves gutter, crossing the conductor wire between both the lug parts and connecting it to the conductor wire provided in the lug parts.

CONSTITUTION: Conductor wires 3, 4 for constituting an antenna with the length of the half wavelength of a receiving frequency are attached respectively in lug parts 2 on both the side upper ends of an eaves gutter 1. A conductor wire 5 is crossed between both the lug parts 2 to connect the conductor wires 3, 4 provided in both the lug parts 2. The conductor wire 3 provided in one lug part 2 is divided at the center thereof and the division part is regarded as the connecting terminal 6 of an antenna. In such a way, the eaves gutter 3 can be constructed and the antenna can be attached. A deviation is not produced in the antenna due to the influence of wind and the like, nor the appearance of a house is deteriorated.
