6. Amplifier Connections and Indicators

Transmit LED:

This LED glows RED in transmit mode indicating that RF power is

applied to the amplifier from the radio.

Receive LED:

This LED glows GREEN in the receive mode when DC power is

applied to the amplifier and is off when transmitting.

DC Injector

Connection:

This “N” Female connector is connected to the DC Power Injector

via the transmission cable.

Antenna Connection:

This “N” Female connector connects to the antenna with a short

length of coax cable.

7. DC Power Injector Connections and Indicators

A DC Power Injector is an in-line device which “injects” the DC power necessary to operate the

amplifier onto a transmission line. This allows the cable to carry both RF signals and DC

power to the mast mounted amplifier.

Transmit LED:

This LED glows RED when the pole mounted amplifier goes into

the transmit mode. The Remote Transmit LED is driven by unique

circuitry, which actually detects changes in the DC current

traveling through the transmission line to the amplifier.

Receive LED:

This LED glows GREEN when DC power is applied to the

amplifier and it is in the receive mode. When toggling between

transmit and receive this LED will glow slightly dimmer.

To Radio Connection:

This “N” Female connector is connected to the radio modem via a

short jumper cable.

To Amplifier

Connection:

This “N” Female connector connects to the amplifier on the mast

via the transmission line.

12 VDC:

This is the DC power input for the injector and is a standard 2.1

mm barrel jack. +12VDC should be applied with center positive.
