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.
The DC Power Injector provides both Power and Remote Transmit Detect
indicator LEDs. The Power LED indicates that the DC Power Supply is
functioning. The Remote Transmit Detect indicator LED detects changes in the
DC current traveling through the antenna feed cable supplying the amplifier.
When the amplifier enters the transmit mode this indicator LED will be
illuminated, providing positive indication that the amplifier is functioning properly.
