Clamping apparatus for antenna device

A clamping apparatus for an antenna device, the clamping apparatus comprising:

• a rotation unit configured to rotate an antenna device in a horizontal direction;
• a tilting unit configured to rotate the antenna device in a vertical direction;
• and
• a connection arm configured to rotatably connect at least one of the rotation unit and the tilting unit to a support pole so that the support pole is not positioned on a horizontal rotation path and a vertical rotation path of the antenna device,
• wherein the connection arm comprises:
• an arm body coupled to the support pole;
• and
• an arm branch extending straight in a radial direction of the support pole from an outer side of the arm body, at least one of the rotation unit and the tilting unit being installed on the arm branch, and
• wherein a rotation center axis of the tilting unit is positioned within an immediately lower range corresponding to a portion between one side of the arm branch close to the antenna device and the other side positioned opposite to the antenna device, and the rotation center axis of the tilting unit does not deviate from the immediately lower range when the antenna device tilts.
