An antenna mounting device configured to collectively mount a plurality of base station antennas on a mast of a communication tower, wherein the antenna mounting device is substantially in the shape of a polygon, and the mast is disposed at a center of the polygon, the antenna mounting device comprising:

• a plurality of brackets, which are elongated and include a head bracket, at least one intermediate bracket and a tail bracket attached sequentially, wherein adjacent ends of the plurality of brackets are pivotally connected together in a head-to-tail manner, each bracket including an antenna connection portion and a mast connection portion connected to each other, wherein the antenna connection portion faces away from the mast and is configured to connect the base station antenna to the bracket, and the mast connection portion faces the mast and is configured to connect the bracket to the mast;
• and
• a bracket fastening mechanism which is disposed between two adjacent ends of the head bracket and an adjacent intermediate bracket, or disposed between two adjacent ends of the adjacent intermediate brackets, or disposed between two adjacent ends of the tail bracket and the adjacent intermediate bracket, and which is configured to move two adjacent ends of the adjacent brackets from a position away from each other to a position close to each other.
