When the user adjusts the height of the lower radiation vibrator 101 and the upper radiation vibrator 103, at this time, The rotating ball 2033 rotates on the surface of the inner ring body 2032. Under the action of the rotating ball 2033, the friction between the lower radiating vibrator 101 and the upper radiating vibrator 103 when adjusting the height is greatly reduced, making it easier and faster for the lower radiating vibrator 101 and the upper radiating vibrator 103 to adjust the height, thereby realizing the function of the dual-band omnidirectional antenna to adjust the lower radiating vibrator 101 with effort, so that when the dual-band omnidirectional antenna is in use, the lower radiating vibrator 101 can be adjusted more effortlessly and quickly, and the dual-band omnidirectional antenna will not be stuck when adjusting the height of the lower radiating vibrator 101, making the dual-band omnidirectional antenna more practical.

[0033] Subsequently, when the omnidirectional antenna body 1 works for a long time, the internal temperature will continue to rise. At this time, the user places the heat conducting plate 301 inside the heat dissipation frame 304, and the user pushes the heat conducting plate 301, so that the heat conducting plate 301 drives the connecting plate 302 to move, and the connecting plate 302 drives the block 305 to slide inside the groove 303. Under the joint action of the block 305 and the groove 303, the heat conducting plate 301 is guided, so that the heat conducting plate 301 is installed inside the heat dissipation frame 304. Under the action of the heat conducting plate 301, the heat inside the omnidirectional antenna body 1 is exported, and then exported to the inside of the omnidirectional antenna body 1 through the heat dissipation through hole 306, and the inside of the omnidirectional antenna body 1 is quickly cooled, so as to realize the function of the dual-band omnidirectional antenna to quickly dissipate the heat inside the omnidirectional antenna body 1, so that the dual-band omnidirectional antenna can quickly dissipate the heat inside the omnidirectional antenna body 1 when in use, so that the use effect of the dual-band omnidirectional antenna is better, and it is not easy to be damaged due to high temperature, and finally the use of the dual-band omnidirectional antenna is completed.
