The conventional antenna mounting tool is good as a mounting tool for a relatively small and lightweight antenna, but in the case of a large and comparatively heavy one such as an antenna for satellite communication, However, it is necessary to increase the number of permanent magnets in a large amount to strengthen the coercive force, which requires man-hours for arranging and adhering each magnet.

If the vehicle exterior surface has icing, dust, or sand adheres to it, the coercive force decreases. It is inevitable that the coefficient of friction with the vehicle surface will decrease due to wax and rainfall. Further, as the temperature of the vehicle surface increases, the magnetic force of the magnet decreases. It is possible for the vehicle to travel at high speed under such environmental conditions, and there have been severe restrictions on usage conditions for the environment such as relative wind speed, vibration, and temperature received by the antenna.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to enhance the magnetic coercive force without increasing the manufacturing man-hours, and at the same time, feel at ease with the environmental conditions described above. An object of the present invention is to provide an antenna mounting tool that can be used by mounting an antenna on a vehicle.

An iron plate or the like having a thickness of about 0.5 mm is used for the magnetic sheet member 3, and the permanent magnet 4 is fixed by an adhesive or an adhesive tape 7. A film sheet 6 made of polyester or the like is fixed to the other surface of the permanent magnet 4 by an adhesive agent or the like to protect the exterior surface of the vehicle. The permanent magnet 4 is formed of a generally used sheet-shaped rubber magnet, for example, which has a large magnetized area, is light in weight, and is effective for following the curved surface of the exterior surface of the vehicle.

When the magnetic sheet member 3 is attached as a back plate on the permanent magnet 4, the magnetic permeability is higher than that without the back plate, so that the gap between the magnet and the iron plate to be attracted is increased. It is generally known that the magnetic flux density becomes higher, the attracting power also improves, and that the higher the magnetic flux density, the more the magnetic flux density raises the attracting power. Regarding this increase in the attraction force, the difference in the attraction force between the case of using two 15 x 40 x 5 (thickness) mm permanent magnets as a sample with a back plate of 5 mm thickness with a gap of 1 mm and without As a result, it was 1.5 times that with the back plate as compared with the case without the back plate.
