Abstract
The utility model provides a short-wave whip-shaped double-frequency antenna including a mounting support, a low-frequency antenna body and a high-frequency antenna body. The low-frequency antenna body is arranged on the mounting support and is connected with the mounting support through a connection piece. The high-frequency antenna body is arranged on the low-frequency antenna body and is connected with the low-frequency antenna body through a connection piece. The low-frequency antenna body and the high-frequency antenna are both connected with coaxial cables. A damping device is arranged between the mounting board and the low-frequency antenna body. A glass steel outer shade is arranged outside both of the high-frequency antenna body and the low-frequency antenna body. The short-wave whip-shaped double-frequency antenna provided by the utility model adopts a double-frequency design and is therefore wide in working frequency band and comparatively large in directivity angle, so that communication blind areas can be eliminated. The high-frequency antenna body and the low-frequency antenna are in threaded connection, so that the short-wave whip-shaped double-frequency antenna is easy to dismount and install. At the same time, since the glass steel outer shade are arranged outside both of the high-frequency antenna body and the low-frequency antenna body, waterproof performance and radio resistance of the antenna are improved.
