In other words, the second connecting portion 57 is attached alternatively from the holding portions 47 and 48.

  Further, the second connection portion 57 is exposed to the outside of the first connection body 41 by being held by the second holding portion 48. The power supply path 55 is connected to the second connecting portion 57 in this state (the second connecting portion 57 is held by the holding portion 47). In other words, the first connecting body 41 has a through hole (second holding portion 48) for connecting the power supply path 55 to the cable 87 in the second end surface portion 46 b (lower portion attached to the eaves 1). .

  In providing the second holding portion 48, the gutter antenna 3 is exchanged from the first connecting body 41 having the first holding portion 47 to another first connecting body 41 having the second holding portion 48. For example, a through hole may be formed at a construction site or the like.

  For this reason, when it hold | maintains with the 2nd holding | maintenance part 48, compared with the case where it hold | maintains with the 1st holding | maintenance part 47, it is easy to approach the 2nd connection part 57 of the electric power feeding path 55 to the said insertion hole for the cables 87 of the building 8. can do. In other words, the gutter antenna 3 is connected to the cable 87 with the second connecting portion 57 held by the second holding portion 48 so that the second connecting portion 57 is exposed toward the eaves 1 side. Can do. For this reason, the gutter antenna 3 can suppress the lead-out length of the cable 87 to the eaves side or the lead-out length of the feeding path 55. Thus, in this case, the cable 87 and the power supply path 55 can be made difficult to loosen, and it is easy to reduce the cable 87 and the like being shaken by the wind. For this reason, the cable 87 can be less likely to be detached from the second connection portion 57 due to the shaking of the wind, or to have noise caused by the cable 87 hitting the roof surface.

  Further, the through hole 48 for connection between the power supply path 55 and the cable 87 may be the first holding portion 47 that fixes the second connecting portion 57 in a state where the second connecting portion 57 is exposed to the outside (downward). In this case, rainwater or the like attached to the cable 87 can hardly reach the second connection portion 57 or the connection portion of the cable 87 through the cable 87, and it is difficult to attach rainwater or the like to the second connection portion 57 or the like. can do. In addition, the gutter antenna 3 is not limited to the case where the through hole 48 is formed at the construction site or the like when the gutter antenna 3 is attached to the eaves 1, and the first connection body 41 is replaced with the first connection body 41 (main body provided with the through hole 48. Part 43) may be replaced.

  In this embodiment, when the gutter antenna 3 is attached to the eaves fence 1, a cap that covers the end opening of the second connection body 42 is provided at the end of the second connection body 42 opposite to the housing 30. It is preferable to provide it. In this case, the cap can suppress the invasion of garbage such as fallen leaves and insects into the housing 30.

  Further, in the present embodiment, when the gutter antenna 3 is attached to the eaves 1, the second connecting portion 57 is replaced from the first holding portion 47 to the second holding portion 48. For this reason, in the state where the rain gutter antenna 3 is attached to the eaves 1, the power supply path 55 does not expose the second connection part 57 to the first end face part 46 a side, and can make it difficult to attach rain water or the like.

  Moreover, in this embodiment, the attaching part 7 may be provided in each suspender 2, or may be selectively detachable from the plurality of suspenders 2. In this case, the suspension tool 2 to which the gutter antenna 3 is attached can be selected from the plurality of suspension tools 2. In other words, in this case, the attachment position of the rain gutter antenna 3 can be selected from a plurality of locations in the longitudinal direction (eave direction) of the eaves 1. Thereby, in this case, it is possible to easily adjust the reception sensitivity and the like of the antenna unit 50.

  The covering 36 may be omitted. Further, although the antenna unit 50 is provided on the outer surface of the cylindrical part 32, the antenna unit 50 may be provided on the inner side in the thickness direction of the cylindrical part 32, the inner surface of the covering 36, or the like. I just need it. The antenna unit 50 is not limited to a substantially C-shaped horizontal cross section, and the antenna unit 50 may be configured by an antenna other than the slot antenna.

  Moreover, the attachment structure of the rain gutter antenna 3 may provide the attachment part 7 in the drain 14, as shown in FIG. In this example, the attachment portion 7 is provided at the upper end of the dust removal portion 15. In the plan view, the drain 14 has a distance from the eaves side end portion 82 to the eaves end of the building 8 is larger than the distance from the eaves end 82 to the eaves end. In other words, the eaves-side end portion 82 is located between the drain 14 and the eaves tip in a plan view. And the eaves side edge part 82 is located in the opening (between both ends of U character) of the eaves bowl 1 in planar view.

  The attachment portion 7 is provided at this portion (the upper end of the dust removal portion 15) instead of the overflow portion 17. For this reason, the attachment part 7 protrudes upward from the rib 16 (the upper end of the dust-removal part 15). And when attaching the gutter antenna 3 to the attachment part 7 of the drain 14, it is comprised so that the eaves side edge part 82 may be located between the gutter antenna 3 and the said eaves edge in planar view. In other words, the eaves-side end portion 82 is configured to be located closer to the ridge than the gutter antenna 3. Furthermore, when the gutter antenna 3 is attached to the eaves 1, the antenna unit 50 can be positioned at a higher location than when attached to the eaves 1. Thereby, in this case, the influence of the surrounding environment and the like can be easily reduced, and the reception sensitivity and the like of the antenna unit 50 can be easily improved.

  Further, when the attachment portion 7 is provided on the drain 14, the load of the gutter antenna 3 is applied to the drain 14, so that the rib 16 is thicker than the drain 14 having the overflow portion 17, and the drain 14 It is preferable to improve the strength. In addition, when attaching the gutter antenna 3 to the drain 14, in order to support the gutter antenna 3 with the eaves gutter 1, the gutter member 10 is formed of a metal member such as iron (for example, a metal is used for the core material). It is preferable to improve the strength of the flange member 10.

  The present invention is not limited to the above-described configuration, and can be implemented with appropriate modifications within a range not departing from the gist.
