Therefore, for example, in ordinary houses, antennas are installed quite high on the roof. The method of installing the antenna in this case is as shown in FIG.
A common method is to hold the pole 4 in place and fix it by pulling the pole 4 from three or four sides with wires 42.

[Problem to be solved by the invention]

However, in the conventional installation method as described above, the mounting of the pedestal 41 on the roof R is unstable, and therefore the work of erecting the pole 4 is unstable, and it is difficult to erect the pole on the roof with poor footing. There have been problems in that the work of fixing the pole 4 with the wire 42 is difficult and dangerous, and that at least two people are required to perform this work. Furthermore, the wire 42 for fixing the pole 4 and the feeder line F running over the roof R caused the problem that the exterior of the building became unsightly.

By the way, as a device for natural ventilation or forced ventilation of an attic, the applicant of the present application has conventionally developed a structure that includes a base in the shape of one or more roof tiles and a cylindrical part that communicates between the top and bottom of the base. ventilation equipment is provided. It is effective to install this ventilation system on the south side of the roof to increase ventilation efficiency. On the other hand, the antenna described above is installed on the roof. In particular, Japan's broadcasting satellites are located in geostationary orbit above the southern part of the Japanese archipelago, and BS antennas (satellite broadcasting receiving antennas) are often installed on roofs facing south.

Therefore, the present invention provides an antenna mounting device that is installed on the roof, and an attic ventilation device that is also installed on the roof, in order to facilitate the installation work of the antenna and improve the appearance of the area around the bottom end of the pole. The aim is to unify the roof and make the roof area even cleaner.

[Means to solve the problem]

In order to achieve the purpose, the attic ventilation system with an antenna mounting part of the present invention is provided with an antenna mounting part on the upper part of a base installed on the roof, and a cylindrical part communicating between the inside and outside of the roof on the base. It is characterized by having been established.

The cylindrical portion may be provided with a ventilation fan to provide a forced ventilation system, or may not be provided to provide a natural ventilation system.

Furthermore, by making the base in the shape of a roof tile, the present device can be installed by replacing one roof tile.
