5. Amplifier Connections and IndicatorsCAUTION: Only use high quality N-type connectors. Do not use PL259 “CB” type UHFconnectors. Doing so will ruin the N-Female jacks and void your warranty.This LED glows RED when the amp has switched to the transmit mode.This occurs when the amp detects RF power at the jack labeled “ToDC Injector”. (See Section 9 operation for more information)This LED glows GREEN in the receive mode when DC power is appliedto the amplifier. It is goes off when; the amp is in the transmittingmode.This N-type female connects to the DC Power Injector via the transmis-sion cable. The length of this cable will determine the type of cablethat should be used. See the installation diagram and the Appendix formore information.Transmit LED:Receive LED:AntennaConnection:DC InjectorConnection:6. DC Power Injector OperationA DC Power Injector is an in-line device which “injects” the DC power necessary to operatethe amplifier onto a transmission line. This allows the coax cable to carry both RF signals andDC power to the mast-mounted amplifier. This precludes the need to run a separate powercable to the remote mounted amplifier.Page 5This N-type female connects to the antenna with a short length oflow-loss coax cable.When grounded to a good earth ground through either the grounding stud or mounting flange,the DC Injector will provide maximum lightning protection to your radio modem, wireless LANcard or Access Point.This a1.
