Abstract

The invention discloses an antenna device with a protection structure, relates to the field of signal antennas, and provides the following scheme for solving problems that an existing signal antenna and a rod body are inconvenient to mount and dismount, and the signal antenna is not provided with a protection structure and is easily damaged when encountering wind: the antenna device comprises an antenna main frame and a rod body, and the bottom end of the antenna main frame is fixedly connected with a connecting sleeve; the rod body is arranged at the bottom end of the connecting sleeve in a sleeving mode, and a positioning mechanism is arranged between the connecting sleeve and the rod body. The circumferential side wall of the rod body is fixedly connected with a fixing plate in a sleeving mode, two symmetrically-distributed first telescopic rods are hinged to the circumferential side wall of the fixing plate, and second telescopic rods are slidably arranged in the first telescopic rods in a sleeving mode. The antenna device is novel in structure, the antenna main frame and the rod body of the antenna device are more convenient to mount and dismount compared with a traditional mode, the antenna can be conveniently overhauled and replaced, and the antenna can be effectively subjected to wind-resistant protection by arranging the clamping mechanism, so that the antenna is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of signal antennas, in particular to an antenna device with a protective structure. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. [0003] The signal antenna of cable TV is generally installed...
