The present invention relates to a multi-band combiner which can integrate, as one, antennas having frequency bands different from each other for fire-fighting wireless and mobile communications services. The combiner is constituted as embedded with a duplexer, a multiplexer, and a diplexer to be combined with a service antenna. According to the present invention, the multi-band combiner is positioned at a repeater which transceives a fire-fighting wireless communications signal, a code division multiple access (CDMA) signal, a wide band code division multiple access (WCDMA) signal, a long term evolution (LTE) signal, and a wireless fidelity (Wi-Fi), and the service antenna, combines the fire-fighting wireless signal and the CDMA, WCDMA, LTE, and Wi-Fi signals of each provider, distributes the combined signals into upper and lower frequency bands to be combined. An input/output reference of a wireless repeater is composed of four ports, and an input/output of the multi-band antenna is composed of one port. |
