Description

Portable antenna

Technical Field

The invention relates to a portable station antenna, in particular to an antenna which is frequently disassembled and assembled.

Background

The prior portable station antenna is inconvenient to assemble and disassemble, and redundant components need to be added, for example, a portable antenna and a portable frame device thereof (application number: CN200720155108.3), wherein when the antenna is installed, an auxiliary device portable frame rod needs to be installed, so that the complexity in the installation process is increased, and the installation time is too long. Or the whole structure of the antenna is not compact enough, and the structure is as in the patent of 'a portable station antenna' (application number: CN201510252088.0), wherein the base of the antenna is higher, and the antenna structure is relatively larger for the antenna with the same caliber. The patent 'single portable offset feed satellite antenna' (application number: CN201010263497.8) is used for being carried on the back by a single person, so the caliber of the antenna has certain size limitation.

In this embodiment, a person skilled in the art can know how to stack the removable antenna panel and its antenna assembly in a plurality of transport boxes after removing them. Of course, it will be understood by those skilled in the art that the antenna may be disassembled and assembled in different ways and different assembling and disassembling structures due to different specifications and/or models of the antennas used, and therefore, the description of the parts is omitted.

In the embodiment of the present invention, a preferred implementation manner is that, corresponding to the transportation box, a square box numbered 1-5 in fig. 1 can be adopted, the square box can be a hexahedron, for this implementation, the

square box

1, 2, 3, 5 stores the antenna face flap and other related components, and the square box 4 is used for azimuth drive, pitch drive, system power supply and driver storage of the system. In the separated transportation state, the 5 square boxes can be fixed on a vehicle for transportation through a fixed rope, and can also be placed in a non-driven vehicle and airdropped to a specified position.
