Abstract

본 발명은 지하 종합무선중계기용 콤바인에 관한 것으로, 특히 터널, 지하상가 및 지하주차장 등의 지하구조물에서는 지표나 건축구조물에 의해 공중으로부터 도래하는 전파가 흡수 또는 전제강도의 약화로 인하여 송수신이 사실상 어려운 실정인 것을, 다수의 수신안테나를 갖는 종합무선중계기용 콤바인을 지하구조물내에 설치함으로써 지상과 동일한 공중파의 송수신를 할 수 있도록 한 것이다.The present invention relates to a combine for an underground wireless repeater, and particularly in underground structures such as tunnels, underground shopping malls and underground parking lots, radio waves coming from the air by surface or building structures are difficult to transmit or receive due to weakening of the overall strength. In this situation, a combined radio repeater combine having a plurality of reception antennas is installed in the underground structure to allow the transmission and reception of the same airwaves as the ground.

즉, 다수의 공중파를 각각 송수신할 수 있는 다수의 송수신안테나(10)와, 상기 다수의 송수신안테나(10)로부터 전송수단(11)을 통해 다수의 공중파를 전송받는 안테나측 콤바인(20)과, 상기 안테나측 콤바인(20)에서 통합되어 전송된 다수의 주파수를 분리하는 입력측 콤바인(30)과, 상기 입력측 콤바인(30)의 출력단(41∼45)으로부터 분리된 미약한 주파수를 고주파신호로 증폭하는 증폭수단(50)과, 상기 증폭수단(50)에서 충분히 증폭된 고주파신호는 해당되는 주파수로 손실없이 하나의 피더라인(80)으로 전송하는 출력측 콤바인(70)으로 구성한 것이 특징이다.That is, a plurality of transmit and receive antennas 10 capable of transmitting and receiving a plurality of air waves respectively, an antenna side combiner 20 receiving a plurality of air waves from the plurality of transmit and receive antennas 10 through a transmission means 11, Amplifying the input side combiner 30 for separating a plurality of frequencies integrated and transmitted by the antenna side combiner 20 and the weak frequencies separated from the output terminals 41 to 45 of the input side combiner 30 with a high frequency signal. The amplifying means 50 and the high frequency signal sufficiently amplified by the amplifying means 50 are characterized in that the output side combiner 70 is transmitted to one feeder line 80 without loss at a corresponding frequency.
