The embodiment of the invention provides a shunt tower and antenna feed system, which relates to the field of communication. By adding shunt tower on the side of antenna unit, the RU of four ports can be realized while ensuring the coverage of the network and improving the network performance. The shunt tower amplifier includes the first filter module, the second filter module, the first amplifier module, the second amplifier module, the control module, the first shunt module and the second shunt module. The first filter module is connected with the first amplifier module, the first amplifier module is connected with the control module, the control module is connected with the second amplifier module, and the second amplifier module is connected with the second filter module. The first shunt module is connected with the first filter module and the first amplifier module; the second shunt module is connected with the second filter module and the second amplifier module; the first shunt module and the second shunt module are used for transmitting signals.
