Clamping apparatus for antenna

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.
