Alternatively, the detachable connection may also be a snap-fit connection. For example, a hook may be disposed on the antenna body 10, and a buckle matched with the hook may be disposed on the supporting rod 20, or a buckle may be disposed on the antenna body 10, and a hook matched with the buckle may be disposed on the supporting rod 20, so that the antenna body 10 is connected with the supporting rod 20 through the cooperation of the hook and the buckle.

The connection mode has the characteristic of convenient disassembly, so that a user can conveniently disassemble the antenna body 10 from the supporting rod 20, and repair or replace the antenna body 10, thereby saving the maintenance cost of the antenna body 10.

In yet another possible implementation, the antenna body 10 and the support rod 20 may be connected in a non-detachable manner.

Alternatively, the non-detachable connection may be a weld. The antenna body 10 is connected with the support rod 20 through welding, the connection performance between the antenna body 10 and the support rod 20 is good, and the strength of the structure is high.

By way of example, the type of welding may be arc welding; the type of welding may also be gas welding, as an example, and the utility model is not limited in this regard.

Alternatively, the non-detachable connection may also be adhesive. The antenna body 10 and the support rod 20 are connected by adhesion, and the stress concentration on the adhesion surface of the antenna body 10 and the support rod 20 is small, so the fatigue resistance is good.

In some embodiments, as shown in fig. 5, the antenna 100 further comprises: a base 90, the base 90 is connected to one end of the support rod 20, and is located on the side of the second annular connecting member 35 away from the first annular connecting member 34. In the embodiment of the present utility model, one end of the support rod 20 is connected with the base 90, and the base 90 can be fixed on the ground or the floor by penetrating through the connecting hole pre-opened on the base 90 by using a screw, a bolt, a screw or other connecting piece, so as to increase the contact area between the support rod 20 and the ground, thereby improving the structural stability of the antenna 100.

The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any changes or substitutions within the technical scope of the present utility model should be covered by the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
