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 a
Transmit indicator LED. The Power LED indicates that the DC Power Supply is
functioning. The Remote Transmit indicator LED detects changes in the DC
current traveling through the antenna feed cable supplying the amplifier. When
the amplifier enters the transmit mode the Transmit LED will be illuminated. This
provides positive indication that the amplifier is functioning properly.
