Teletilt ® Remote Electrical Downtilt SystemRET System With Smart Bias Tees Using SMB PortsThe Teletilt ATC300-1000 rack mount controller provides an additional option for injecting the AISGsignal into the RF cable. The new family of dc 2.1 bias tees are used as an alternative to smart biastees when using the SMB ports on the controller instead of the AISG connection.There are two options that can be used for dividing out the AISG signal from the RF cable intocontrol cables leading to the antenna line devices at the top of the site. One option is to use asmart bias tee at the top. The AISG port on that smart bias tee can be connected to a junction box,actuator, or any other RET device. A second option is to use an AISG tower mounted amplifier (TMA),which also has an AISG port for connecting to any RET devices.RET System Using SMB Ports on ATC300-1000 with Either a Smart Bias Tee oran AISG TMA at the TopSmart Bias TeeOptionTMAOptionAntennaSmart Bias TeeAISGTMAActuatorAISGControlCableCoaxial cable for SMB/SMA PortsCoaxialCableAISG CoaxialSurge Arrestordc 2.1 Bias TeeATC300-1000ControllerCrossoverEthernetCableorNetworkAISG ConnectorSix SMB JackConnectorsBTS(Computer interface not supplied.)Andrew Wireless Solutions www.andrew.com83
