For automatic control, the short-wave antenna 100 further includes a control component (not shown), and the control component is in signal connection with the rotating component 20, the supporting component 30, and the antenna component 40, respectively.

Then, the tractor 11 backs up a little bit backwards, the control assembly controls the first lifting power element 28, the second lifting power element, the third lifting power element and the fourth lifting power element to extend further, and the fixing member 21 is leveled while the rotating member 22 is disengaged from the tractor 11 by the connecting pin of the rotating member 22 and the tractor 11 runs forwards and is disengaged from the rotating member 22. The second folding arm 34 is removed from the connecting pin of the axle 12 and the axle 12 is retracted and disengaged from the second folding arm 34.

As shown in fig. 3, the control component controls the extension of the folding power element 35, the folding power element 35 drives the first link and the second link to synchronously rotate, so that the first folding arm 31 rotates around the second folding arm 34, meanwhile, because the rotating component 22 is fixed, the first folding arm 31 drives the pull rod 32 to move upwards, and then under the traction of the pull rod 32, the first folding arm 31 and the second folding arm 34 move upwards until the first folding arm 31 and the second folding arm 34 are in a straight line, at this time, the second folding arm 34 is perpendicular to the rotating component 22, as shown in fig. 4. During the extension of the folding power element 35, the stretching power element 39 controls the length of the stretching element 38, so that the stretching element 38 keeps a stretched state.

After the first folding arm 31 and the second folding arm 34 are completely unfolded, as shown in fig. 5, the stretching power element 39 shortens the stretching member 38, so that the stretching member 38 drives the first supporting arm 33 to rotate around the first folding arm 31 and simultaneously drives the antenna assembly 40 to rotate together until the first supporting arm 33 and the first folding arm 31 are aligned.

As shown in fig. 6, when a signal needs to be received or transmitted by unfolding, the first telescopic power element lengthens the first telescopic member 43, and since the antenna layers are fixed by the telescopic members, the second antenna layer 42, the third antenna layer 44 and the fourth antenna layer 45 all rotate around the first supporting arm 33 until the included angle between the first antenna layer 41 and the second antenna layer 42 is 10 degrees, the third antenna layer 44 and the fourth antenna layer 45 operate in sequence in the same manner, fig. 7 is an unfolding schematic diagram of the third antenna layer, and fig. 8 is an unfolding schematic diagram of the fourth antenna layer.
