The threaded mounting block connected to the outside of the signal plug can install and position the control body. At this time, the upper and lower sides of the rubber plate are tightly attached to the control body and the base plate respectively, thereby sealing the shell and the base plate, making the antenna device more stable in use; 2. In this application, through the setting of a base, placement slot, signal connection spring, connection slot, horizontal slot, vertical slot, signal connection rod, horizontal omnidirectional dipole antenna body, mounting slot, through hole, conductive block, arc groove, horizontal plate, insert strip, vertical plate, rubber plate, retaining ball, deformation slot, convex block, circular dual-frequency microstrip antenna, connection block, sliding groove, connection plate, retaining plate, cylindrical shell, rubber column, push spring, and circular hole, the signal enters the horizontal omnidirectional dipole antenna body through the signal connection spring, and the external signal is transmitted through the horizontal omnidirectional dipole antenna body. The signal enters the circular dual-frequency microstrip antenna through the signal connection rod and connection block, and the signal is transmitted vertically through the circular dual-frequency microstrip antenna, making the signal transmission range of the UAV wider. The elasticity of the rubber plate pushes the retaining ball into the arc groove opened in the horizontal omnidirectional dipole antenna body, thereby improving the horizontal omnidirectional dipole antenna body. The horizontal positioning system makes the horizontal omnidirectional dipole antenna body more stable during use. By setting the connecting plate and the clamping plate in the mounting slot of the horizontal omnidirectional dipole antenna body, the connecting block can be installed above the horizontal omnidirectional dipole antenna body. At this time, the push spring pushes the cylindrical shell and the connecting plate with its own elastic force to prevent the connecting plate from moving and to prevent the connecting plate and the connecting block from falling off. The rubber column can limit the push spring set at one end of the outer side of the cylindrical shell to prevent the push spring from bending and make the push spring contraction process more stable. The horizontal plate and the insert can limit the rubber plate in the vertical direction, and the vertical plate can limit the rubber plate in the horizontal direction to prevent the rubber plate from falling off the mounting slot of the base. The convex block can facilitate the sliding of the horizontal plate above the vertical plate, which is convenient for the disassembly and replacement of the rubber plate. At the same time, the deformation groove can increase the deformation of the rubber plate and make the movement of the clamping ball more stable. 3、In the application, by setting the signal plug, installation shell, first rubber ring, limit ring, second rubber ring, first rubber ring, second rubber ring, limit rod, mounting column, L-shaped conductive plate, conductive strip, conductive column, cover plate, rubber pad, push block, rubber strip, deformation hole and forming die groove, the signal line can be inserted into the mounting column, then the signal line is bent into a U-shaped sleeve outside the conductive strip, the cover plate is installed into the mounting column, at this time the push block pushes the rubber strip to limit the signal line, the signal line is closely attached to the L-shaped conductive plate and the conductive strip, the rubber strip clamps the signal line through the elasticity of the L-shaped conductive plate, to prevent the signal line from falling off, after the mounting column is installed into the installation shell, the installation shell can limit the cover plate, and the mounting column can be screwed outside the signal plug at the same time, at this time the signal line transmits the signal to the signal plug through the L-shaped conductive plate, the conductive strip and the conductive column, the mounting column and the signal plug can clamp the second rubber ring, the second rubber ring is deformed under the action of the forming die groove, to seal between the mounting column and the signal plug, the cover plate is limited by the limit rod, so that the cover plate and the mounting column clamp the rubber pad, the rubber pad is closely attached to the cover plate and the mounting column, to seal the inside of the mounting column, after the mounting column and the signal plug are installed, the mounting column pushes the installation shell and the first rubber ring upward through the limit ring, at this time the top of the first rubber ring is closely attached to the bottom plate, the top of the second rubber ring is closely attached to the installation shell, then the first rubber ring is pushed into the mounting hole of the installation shell, the installation shell is sealed by multiple layers of sealing, so that the electrical connection is more stable.
