Definitions

  • the invention relates to the field of antenna fixing systems, and more particularly, to antenna fixing systems provided for fixing an antenna such as a base station to a pole.
  • Base station antennas for mobile telephony are commonly fixed to poles provided on rooftop sites, towers or on walls.
  • the installation is an effortful work process for installation personnel.
  • an installation process is aggravated since heavier active antennas are installed. Therefore, the installation process shall be facilitated by improving antenna mounting brackets, e.g. in order to setup heavy equipment without requiring any extra tools.
  • an antenna fixing system comprises an antenna mounting bracket for receiving the antenna, a pole adaptor having a first side configured to partly embrace poles of a first diameter range and a second side configured to partly embrace poles of a second diameter range, a first connecting element and a second connecting element for tightening the pole adaptor to the antenna mounting bracket with the pole being clamped between the antenna mounting bracket and the first or the second side of the pole adaptor.
  • the pole adaptor is rotatably supported by the first connecting element to be rotatable around a length axis of the first connecting element and comprises a first hinge to be rotatable around a rotation axis being normal to the length axis of the first connecting element.
  • an appropriate side of the pole adaptor for embracing the actual pole can be selected without dismantling an assembly of the antenna mounting bracket, wherein the pole adaptor and the first and second connecting element can be preassembled under comfortable circumstances.
  • the first diameter range is different from the second diameter range, and the first diameter range and the second diameter range partly overlap.
  • a large overall range can be covered by the antenna fixing system. It is assumed that a diameter A of a pole is the smallest diameter which can be partly embraced by the first side still enabling a clamping function and a diameter C is the largest diameter which can be partly embraced by the first side. Further, it is assumed that a diameter B is the smallest diameter which can be partly embraced by the second side still enabling a clamping function and a diameter D is the largest diameter which can be partly embraced by the second side. Furthermore, diameter C is larger than diameter B. Hence, diameters A and D define boundaries of the overall range and diameters B and C define an overlapping range of the diameters which can be embraced.
  • the antenna mounting bracket comprises at least one second hinge for supporting at least one of the first connecting element and the second connecting element pivotably with respect to the antenna mounting bracket.
  • the antenna mounting bracket is provided with at least one stopper for limiting the pivoting of the connecting element.
  • the first side of the pole adaptor and the second side of the pole adaptor have different shapes, i.e. a narrow shape and a broad or wide shape.
  • the different shapes of the first and second side of the pole adaptor enable a better fitting of the respective side to a respective diameter range.
  • the first side comprises a first-side-clamping section for clamping the pole and has a first-side- contact face connection line connecting a centre of a first-side-contact face, e.g.
  • the first-side-contact face being configured to receive an urging force of the first connecting element and a centre of a further first-side- contact face, e.g. corresponding to a centre line of clamping bolt, the further first-side-contact face being configured to receive an urging force of the second connecting element in a first orientation of the pole adaptor

  • the minimum distance between the first-side-contact face connection line and the pole clamped by the second-side clamping section in the first orientation is different from the minimum distance between the second-side-contact face connection line and the pole clamped by the first-side clamping section in the second orientation
  • clamping of the different diameter ranges can be achieved without large displacement of the pole adaptor on the connecting elements and, therefore, e.g. minimum screw lengths can be used.

  • the pole adaptor is provided with an open slotted hole removably engaging the second connecting element.
  • a method for fixing an antenna to a pole with the use of an antenna fixing system comprises the steps: selecting an orientation of the pole adaptor preassembled to the antenna mounting bracket such that the first side or the second side of the pole adaptor faces the antenna mounting bracket; and exerting an urging force to the pole adaptor so that the pole is clamped between the antenna mounting bracket and the pole adaptor.
  • the side suitable for embracing the actual pole diameter can be easily selected and the antenna mounting bracket with the pole adaptor in the suitable orientation can be easily mounted to the pole without large efforts for adjusting the antenna fixing system to the pole diameter.
  • the orientation of the pole adaptor is selected by pivoting the pole adaptor around the length axis of the first connecting element and around the rotation axis being normal to the length axis of the first connecting element.
  • the selection of the suitable orientation of the pole adaptor can be done without separating the pole adaptor from the antenna mounting bracket.
