[For use]

In the present invention, the conductor wires 3 and 4 constituting the antenna are integrally provided in the ear part 2 of the eaves gutter 1, so that the eaves gutter 1
At the same time as the construction, work to fit the antenna must be done outside, and since the antenna is built into the eaves gutter 1, the antenna may become distorted due to the influence of wind, or the antenna may damage the house. It does not damage the appearance of the product. Further, the conductor wires 5, 5, which are stretched between the ears 2, 2 to connect the conductor wires 3, 4, make it possible to reinforce the eaves gutter 1 by preventing the upper part of the eaves gutter 1 from widening.

【Example】

The present invention will be explained in detail below with reference to Examples. The eaves gutter 1 is made of a synthetic resin material having electrical insulation properties, and ears 2 are integrally provided at the upper ends of both sides thereof. FIG. 1 shows an embodiment of the present invention,
A conductor wire 3 made of copper, iron, stainless steel, etc. inside each ear part 2, 2,

4 can be attached by being inserted into the hollow portion when the ear portions 2, 2 are formed hollow, or can be inserted into the wall thickness of the ear portions 2, 2 and removed. By providing the conductor wires 3 and 4 inside the ears 2 and 2 in this way,
There is no risk of any effect on drainage, which is the original function of the eave @ 1, and the conductor wires 3 and 4 in the ear part 2
Because it is protected, corrosion can be prevented from occurring. The length of each conductor wire 3, 4 is set according to the wavelength range of the radio wave to be received, and is set to the length of a half wavelength (172λ) of the radio wave. Also, both ends of the conductor wire 3 provided in one ear 2 and the other ear 2
Both ends of the conductor wire 4 provided inside are connected to each other by conductor wires 5.5. The conductor wires 5, 5 are stretched within the upper end of the eave gutter 1 so as to span between the ears 2, 2, and within the ears 2, 2, the conductor Ii! 3.4 and conductor wire 5
, 5 are integrated. The conductor wire 3 provided on one ear 2 is divided at the center in the direction of the technique so that it is separated into a pair of conductor wires 3a, 3a, and each conductor wire 3a, 3a is The ends on the split side are led out from the ears 2 to the outer surface of the eaves gutter 1 as connection terminals 6, 6. A balun transformer 10 is attached to the connecting terminal 6.6, and a connection #i11 such as a coaxial cable or Figu wire is attached to the balun transformer 10 to electrically connect the connecting terminal 6 and the connecting wire 11. As described above, a closed loop dipole antenna formed by the conductor wires 3, 4.5 can be provided in the eaves gutter 1. Folded dipole antennas have the advantage of having a wider receiving wavelength range than non-closed loop antennas. Note that the conductor wire 3a. 4.5 can be formed by one continuous line. By installing the antenna-equipped eaves gutter A formed as described above in the same manner as other general eaves gutter,
When installing the antenna-equipped eaves gutter A, the antenna can be installed at the same time as the installation. Furthermore, if this eaves gutter A with an antenna is installed at the optimum position as an antenna, there is no risk of positional deviation due to the influence of natural factors, etc., and there is no possibility that the receiving sensitivity of the antenna will decrease. Furthermore, although the eaves gutter 1 made of synthetic resin is easily deformed so that its upper end opens due to the effects of high temperatures in summer, the eaves gutter 1 is stretched between the upper ends of the eaves gutter 1 to form a closed loop dipole antenna. It is possible to prevent such deformation from occurring by the conductor wires 5, 5. FIG. 2 shows how the antenna-equipped eaves gutter A is installed. In FIG. 2, 12 is the roof of a house, 13 is a general eaves gutter, and 14 is a rainwater outlet. As shown in FIG. 2, the eaves gutter A with an antenna only needs to be used at a location suitable for installing an antenna, and can be connected to other general eaves gutter 13 using an eave gutter joint or the like.
