されている。(Summary of Embodiments) The following is a summary of the configuration and operational effects of the three-wave shared antenna device shown in the embodiments. [1] The three-wave shared antenna device of the present embodiment can receive GPS broadcast waves on the mounting base F of the AM / FM receiving antenna (10, 30, 50) capable of receiving AM broadcast waves and FM broadcast waves. The GPS receiving antenna 20 is integrally mounted.

Since the PS receiving antenna 20 is integrally mounted on the mounting base F of the AM / FM receiving antenna (10, 30, 50) and capable of receiving three waves, the GPS receiving antenna 20 is newly provided. In spite of this, there is no fear that the mounting work on the mounting target such as the vehicle body will become complicated. Further, since the GPS receiving antenna 20 is mounted in a compact state at the base portion of the AM / FM receiving antenna 10 and the like, it is unlikely to be a cause of poor appearance and contact failure. [2] The three-wave shared antenna device according to the present embodiment has the above-mentioned [1].
The device according to claim 1, wherein the AM / FM receiving antenna (1
0, 30, 50) are rod-shaped antenna elements (11, 31,
51) is a vehicle antenna, and GP is installed inside the case (13, 33, 53) of the mounting base F to which the base ends of the rod-shaped antenna elements (11, 31, 51) are joined.
An S receiving antenna 20 is housed.

る。In the three-wave common antenna device, the base end portions (12, 32, 52) of the rod-shaped antenna elements (11, 31, 51) in the vehicle AM / FM receiving antennas (10, 30, 50) are mounted on the vehicle body. G is attached inside the case (13, 33, 53) of the mounting base F for mounting and fixing to the wall W.
Since the PS receiving antenna 20 is housed, so-called dead space is effectively used, a new installation space is not required, and the existence of the GPS receiving antenna 20 cannot be recognized from the outside of the case 13. Therefore, it is advantageous in terms of theft prevention. Further, the GPS receiving antenna 20 is sufficiently protected from wind and rain by the wall of the case 13.
