Detailed Description

With the increase of frequency, the difficulty of antenna exchange becomes larger and larger. For example, in the E-band of the antenna, the final received power is greatly affected if the antenna is slightly off-center. The spacing between base stations is large, e.g., three kilometers. When the antennas are adjusted oppositely, operators need to assist by means of a telescope to observe whether the antennas are adjusted in place or not due to the fact that the distance between the base stations is large.

It will be appreciated that due to unavoidable process errors, the antenna electrical axis 301 may be offset from the central axis of the main lobe of the antenna 33 by an angle, for example, the antenna electrical axis 301 may be offset from the central axis of the main lobe of the antenna 33 by about 5 degrees (e.g., as shown by region 305 in fig. 4).

Referring again to fig. 1, 5 and 6, the auxiliary device 60 includes a mounting assembly 601 and a telescope 603. The mounting assembly 601 includes a sleeve 62 and a plurality of adjustment members 65.

In this embodiment, the telescope 603 can be a low-cost civil telescope to reduce the cost. Telescope 603 has a sight for aiming. It will be appreciated that the type and kind of telescope 603 is not limited.

The position and the posture of the telescope 603 in the sleeve 62 are adjusted by adjusting the length of each adjusting piece 65 extending into the hollow cavity 621, so that the optical axis 307 of the telescope 603 is coincident with or parallel to the central axis of the sleeve 62, and the optical axis of the telescope 603 is parallel to the antenna electric axis 301 of the antenna 33, therefore, when the antenna is adjusted, the telescope 603 moves along with the antenna device 30, the aiming direction of the telescope 603 is consistent with the antenna electric axis 301 of the antenna device 30, the antenna adjusting precision is improved, and the cost is low.

In the process of exchanging the antenna device 30 of the base station 100 with the antenna device of another base station, the antenna device 30 may be roughly adjusted to a rough position by a device such as a compass and then finely adjusted. During fine tuning, the operator may view another base station (the opposite station) through telescope 603, for example, with a target located at another base station that is within centimeters of base station 1003. Since the optical axis 307 of the telescope 603 is parallel to the antenna axis 301 of the antenna 33, this means that the exchange of the antenna 30 between the base stations 100 is as accurate as required when the sight of the telescope 603 can be aimed at the target's bulls eye.

The first circumference is parallel to the second circumference, and the center of the first circumference and the center of the second circumference are located on the central axis of the sleeve 62, so as to improve the stability of the telescope 603 in the sleeve 62. It is to be appreciated that the present application does not limit all adjustment apertures 623 of the first set of adjustment apertures 6201 to be located on the same circumference, and that the present application does not limit all adjustment apertures 623 of the second set of adjustment apertures 6203 to be located on the same circumference.

Thus, the telescope 603 is stressed more evenly, and the parallelism between the optical axis 307 of the telescope 603 and the central axis 303 of the sleeve 62 is improved, which theoretically can reach 100%. It can be understood that the present application does not limit the included angle formed by the two adjacent adjusting holes 623 of the first group of adjusting holes 6201 or the second group of adjusting holes 6203 and the center of the circle.
