Installing the DC Injector Mounting Bracket:
Install the bracket as shown above using two (2) #10-24 screws and split
lockwashers as shown. For optimal lightning protection, it is recommended that one
screw also be used for attachment of a suitable ground wire.
Connections and Features of The DC Power Injector/ Lightning Protector
The DC Power Injector (also known as a "Bias-T") is an in-line device which
couples DC power onto a coaxial cable, enabling the cable to carry both RF (radio
frequency) signals and DC power. The amplifier is powered remotely through the
coaxial antenna feed cable by the way of this device. The DC Power Injector
included with the kit also provides integral lightning protection.
In addition to a POWER indicator LED, the DC Power Injector provides Remote
Receive and Transmit Detect indicator LEDs. The Power LED indicates that the
DC Power Supply is functioning. The Remote Receive and Transmit Detect
indicator LED detect changes in the DC current traveling through the antenna feed
cable supplying the amplifier. When the amplifier enters the receive mode the
Receive indicator will illuminate. When the amplifier enters the transmit mode the
Receive LED is extinguished and the Transmit LED will be illuminated. This
provides positive indication that the amplifier is functioning properly.
