1. A clamping apparatus for an antenna, comprising:
an arm unit coupled to a support pole and extending in one horizontal direction from the support pole by a predetermined distance;
a common coupling unit detachably mounted to a front end of the arm unit by insertion and detachment operations of a coupling shaft elongated vertically, the common coupling unit being selectively rotatable from side to side about the coupling shaft;
a rotation unit having a front end detachably mounted to a front end of the coupling unit by insertion and detachment operations of a rotary shaft elongated vertically, the rotation unit being rotatable from side to side by a predetermined angle about the rotary shaft; and
a tilting unit coupled to the front end of the rotation unit to be tiltable vertically, an antenna device being coupled to the tilting unit,
wherein the front end of the arm unit is coupled with a fixing shaft hole block to which the coupling shaft of the common coupling unit is axially coupled,
wherein the front end of the arm unit is provided with a brake part configured to form a predetermined frictional force between the front end of the arm unit and the common coupling unit or the rotation unit,
wherein the brake part comprises a lower brake washer pad provided on a lower side of the front end of the arm unit to form a frictional force with a lower bonding surface of the common coupling unit or the rotation unit,
wherein the lower brake washer pad is installed through a washer installation bracket extending from a lower surface of a rear end of the rotation unit.
