1. A parapet-hanging-type antenna mount, comprising: a mount main body that is fixed to an upper part of a parapet on a rooftop of a building; and a vertical support column part that is provided in the mount main body and vertically hangs down along an outer wall surface of the parapet, in which an antenna is installed to the vertical support column part so as not to protrude upward from the parapet,
the parapet-hanging-type antenna mount, comprising:
a horizontal support column part that is provided at an upper end of the vertical support column part and horizontally extends in a direction orthogonal to the parapet toward an inner wall surface side of the parapet; and
a support column holding cylinder that is provided in the mount main body and holds the horizontal support column part such that the horizontal support column part is movable frontward/backward along a central axis in a length direction thereof and is rotatable about the central axis, wherein

the vertical support column part is configured to be pullable to an inner wall side of the parapet by rotating the horizontal support column part about the central axis to place a leading end of the vertical support column part to face heavenward, and moving the horizontal support column part to the inner wall side of the parapet along the central axis,
the support column holding cylinder is provided with: a longitudinal groove that extends in a front-back direction along the central axis; and a lateral groove that extends in a circumferential direction of the support column holding cylinder so as to be continuous with a front end of the longitudinal groove and be orthogonal to the longitudinal groove,
the horizontal support column part is provided with a guide protrusion that is fitted in the front end of the longitudinal groove of the support column holding cylinder in a state where the vertical support column part is located on a front side of the outer wall surface of the parapet and where the leading end of the vertical support column part faces heavenward,
the horizontal support column part is thus configured to be pullable backward while being guided by the guide protrusion fitted in the longitudinal groove, and
a length in a circumferential direction of the lateral groove is set such that:
in a state where the guide protrusion fitted in the longitudinal groove is located at the front end of the longitudinal groove, the horizontal support column part is configured to be rotatable about the central axis along the lateral groove;
in a state where the guide protrusion is located at a leading end position of the lateral groove, the leading end of the vertical support column part faces vertically downward; and
in a state where the guide protrusion is located at a connection position between the lateral groove and the longitudinal groove, the leading end of the vertical support column part faces heavenward.
