Radio-frequency signal emission antenna

Abstract

A radio-frequency signal emission antenna comprises a storage box and a storage cavity, wherein the storage cavity is formed in the storage box, a mechanical arm device is arranged in the storage cavity and comprises a fixed arm and a rotation arm, the rotation arm is matched with the fixed arm by an expansion gear shaft, the rotation arm can rotate around the expansion gear shaft, the mechanicalarm device comprises a displacement mechanism, and the displacement mechanism is matched with the fixed arm. The device is simple in mechanism and is simple and convenient to use, the device can be started in severe weather such as thunderstorm and high wind to storage a signal antenna; after storage, the wind receiving area can be reduced by the device, and the danger that the signal antenna is blown away is greatly prevented; moreover, after the device is stored, an enclosed box body material is an insulation material, the probability of lightning strike is greatly reduced, and the application safety is ensured; and meanwhile, the device also can be used for automatically rotating and adjusting, and a user is convenient to rapidly adjust an angle when no signal is generated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency signal transmitting antenna. Background technique [0002] Some signal receivers on the ground receive radio frequency signals through their receiving devices for normal use of the equipment. The radio frequency signal transmitters are generally installed at high places, and the signals emitted by them can be received by a wide range of signal receivers. Due to the signal reception The antenna is installed at a high place, and it is easy to be struck by lightning when encountering bad weather, especially lightning weather, while the traditional antenna is fixed, which reduces the signal receiving range. Contents of the invention [0003] In view of the deficiencies of the above technologies, the present invention proposes a radio frequency signal transmitting antenna, which can overcome the above deficiencies. [0004] The present invention is a radio f...

[0002] Some signal receivers on the ground receive radio frequency signals through their receiving devices for normal use of the equipment. The radio frequency signal transmitters are generally installed at high places, and the signals emitted by them can be received by a wide range of signal receivers. Due to the signal reception The antenna is installed at a high place. When encountering bad weather, especially lightning weather, it is vulnerable to lightning strikes, while the traditional antenna is fixed, which reduces the signal receiving range.
