Disclosed is a tower top amplifier directly and detachably attached and electrically connected to an antenna of a base station for mobile communication. The tower top amplifier includes a tower top amplifying unit (20) connected to an antenna unit (10), and a connecting unit (30) provided on one surface of the antenna unit (10) for connecting the tower top amplifying unit (20) and the antenna unit (10). The tower top amplifying unit (20) is directly attached and electrically connected to the antenna unit (10) without any cable, thereby causing the tower top amplifier to be simply assembled and disassembled. The tower top amplifier does not require the cable exposed to the outside, thus having an aesthetic appearance. The tower top amplifying unit (20) having the same shape as that of the antenna unit (10) is detachably attached to the antenna unit (10), thereby being formed integrally with the antenna unit(10).
