Abstract

The invention discloses an unmanned aerial vehicle navigation decoy signal generating antenna which comprises an antenna body, and a mounting device is arranged on the left side below the outer wall of the antenna body. The unmanned aerial vehicle navigation decoy signal generation antenna is simple in design structure, convenient for operators to disassemble and assemble, very convenient to operate and capable of reducing the disassembly time, bringing convenience to maintenance personnel and avoiding the waste of time, and the substrate does not need to be taken down by the operators, so that the operation is very convenient, and the maintenance efficiency is improved through the cooperation of the thin tube, the thick tube, the support rod, the handle, the first magnetic plate and the second magnetic plate. Through cooperation of the heat shrink tube and the rubber sleeve, sealing of the connection part of the external wiring and the antenna can be ensured, the connection part of the antenna and the external wiring is prevented from being corroded, normal use of the antenna is ensured, through cooperation of the mesh enclosure and the base, protection of the antenna is realized,and the service life of the antenna is prolonged. External birds are prevented from easily falling above the antenna to defecate and nest, and the service life of the antenna is further ensured.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to an antenna for generating navigation decoy signals for drones. Background technique [0002] The UAV navigation deception simulates the satellite signal emitted by the navigation satellite, and transmits its signal in a directional manner, so that the aircraft receives the decoy signal. The default is the normal navigation signal in the sky. When the position is offset in the analog signal, the aircraft will Moving in the opposite direction is the basic principle of navigation deception, where the signal transmitter is an antenna. [0003] The UAV navigation decoy signal generating antenna in the prior art is fixed by bolts during installation, and the fixing effect is good, but it is not easy to disassemble, especially the antenna in the high altitude, which is easy to be damaged. It is inconvenient for the operators, the connection between the antenna and the external wiring is...
