Further, above-mentioned V-type movable rod is installed the folder sign indicating number by one and is movably attached to described slide block, and this installs folder sign indicating number fixed clamp on described slip pole, and described V-type movable rod is hinged on the described installation folder sign indicating number.
The effect that the folder sign indicating number is installed is to be convenient to the installation of array antenna and to disassemble.
Further, above-mentioned bracing frame further comprises upper support frame and lower support frame, and the both ends of described array antenna are connected to respectively on described upper support frame and the lower support frame.
The both ends of array antenna are connected to upper support frame and lower support frame respectively, make that fixing of array antenna is more firm, simultaneously, by regulating the distance of array antenna upper end and upper support frame respectively, and the distance of bottom and lower support frame, be convenient to the angle of declination of accurate array of controls antenna.
Further, the above-mentioned bracing frame and the installed surface of pole are provided with the second convex guide rail, are provided with U-type strip in this second convex guide rail, and this U-type strip is connected to one by screw bolt and nut and installs on the folder sign indicating number, and this installs folder sign indicating number fixed clamp on described pole.
When array antenna quantity and position change, consider the stress balance of pole, need to regulate the relative distance between fixed mount and the pole, by the cooperation between the U-type strip and the second convex guide rail, can realize the adjusting of the relative distance between fixed mount and the pole, when needs are regulated, unclamp nut, pole is slided into suitable distance, allow the back hold-down nut that pole is locked.
Further, on the above-mentioned bracing frame with parallel plane arbitrary side, described pole place on, be provided with scale.
Scale is set is for the spacing that realizes array antenna and the accurate adjusting of the relative position relation between pole and the bracing frame.
The utility model also can install adjusting device additional, this adjusting device has been used the adjustable mimo antennas of aforesaid a kind of spacing, also comprise electronic-controlled installation and motor, current spacing is calibrated and discerned to this electronic-controlled installation to the array antenna spacing, and transmission instruction CD-ROM drive motor is carried out remote adjustment to the array antenna spacing.
Because it is the needs of the project installation and the network optimization can also be installed electronic-controlled installation and realize that by means of motor its spacing electronics is adjustable after considering on this antenna, but also can be, both convenient but also can save maintenance cost in Long-distance Control.As the pith of system optimization, in general, correlation reduces along with the increase of spacing, can improve the probability of the received power difference increase of two aerial arrays simultaneously, so concerning certain wireless environment, total optimal spacing that adapts under this environment that exists.So under varying environment and demand, its spacing is different.
